| [R] Implementing t-test Functions Posted: 13 Apr 2020 09:48 PM PDT Hello! So for an assignment, I've been tasked with creating three functions in R that correspond to t-tests "of different complexity". Here are the questions: 1) Write a function tScore that takes in two arguments - a vector of samples and a mean under the null hypothesis - and returns a t-score, i.e the difference between the sample mean and null mean, scaled by the estimated standard deviation of the sample mean. 2) Now, write a function called tTest1 that takes in three arguments - a vector of samples, the mean under the null hypothesis, and a character string that will either be 'greater', 'less', or 'equal' - and returns the p-value for the 1-sample t-test. The character string represents the null hypothesis, i.e. 'greater' means the null hypothesis is that the true mean is greater than or equal to the null mean. 3) Ideally, your t-test function would provide the user with more information than just the p-value. Write a function tTest1better that is similar to tTest1 except for the following: * Takes in an extra argument, alpha, that is the 'size" of the test: if the p-value is below this level, we reject the null hypothesis. * Outputs a list (not a vector) with 3 named elements: pVal (the p-value), tScore (the t-score), and reject (a logical that tells the user whether or not the test rejects the null hypothesis at level alpha. So far, I have a solution for the first question that looks like this: I used the professor's hint in the question to come up with that, although I feel like I've seen conflicting formulas online for t-score. So, the biggest questions I have for this assignment as a whole revolve around **finding the correct t-score and p-value formulas.** For question 2, for example, how do I produce and return a p-value that changes depending on the 'greater', 'less', and 'equal' strings? I don't know how this could look in R. There should be a formula for it but all I can find online are automatic p-value calculators, maybe I'm just not looking hard enough. So, what are the true formulas for p-value and t-scores that I can implement in creating these functions? If anyone could point me to a great resource or walk me through this, that would be awesome. Thank you!! :) P.S. I understand this subreddit is more catered towards pure programming and this is more of a Statistics question, but I'm trying my luck in as many subreddits as possible [link] [comments]  |

| Posted: 13 Apr 2020 07:44 PM PDT Hi all, I'm using Python to create a program that can take all the text in a PowerPoint file and then export it into a table in Excel. I'm honestly very lost in how to do this. I've seen tutorials on taking data from Excel to PowerPoint but nothing for the other way around. I use the PPTX module but python cannot read the PowerPoint properly when I input this file. Will somebody guide me? [link] [comments]  |
| TextInput that needs to fetch results stored in database and display them on screen. Posted: 13 Apr 2020 05:58 PM PDT Hello all, I need some help please. I am using myadmin database with php code, and react native for my app. I am in the middle of creating an app that the user inputs a 3 digit number into the textinput box. That number then fetches the results that are already stored in the database (the results are attached to that number. I need for those results to render on my react native screen. Now my fetch method works, so does my php code. I have the results displaying on my screen. But the three problems that I am having is this. (I am using FlatList to render items) -When the results are displayed through my UI they are all on one line. so it will display 3 users. It displays the users like this.......userA<br>userB<br>userC. I want them to display like this.... userA userB userC but they don't and I have tried everything. -Also when the users are displayed the line break is also displayed. I do not want the <br> in between each displayed user. -Lastly when the users are displayed like I have them in the first issue. They are displayed like that on every line of the FLatList....like so.... userA<br>userB<br>userC userA<br>userB<br>userC userA<br>userB<br>userC userA<br>userB<br>userC Again I just want it to only display that actual number of users that are stored in the data that the user called for. And also I want them to be displayed like so userA userB userC Here is my code. It has both the react native javascript code and also my php code. Thank you so much!!! [link] [comments]  |

| Posted: 13 Apr 2020 05:22 PM PDT Hi all, I have some folks with memory issues, and was just wondering if this idea would be possible. I was thinking about creating an app or something to remind them to bring their PPE (glove/mask) when they had to leave their house to head to the store. If the car is new enough, and has bluetooth capability, would it be possible to send a notification to their phone to remind them to bring their PPE when they turn on the car/connect to the bluetooth? I'm not too familiar in this realm, and was just looking for any insight anyone could provide. Thanks! [link] [comments]  |
| How would I make a program that detects when certain pixels on the screen change? Posted: 13 Apr 2020 05:00 PM PDT Hi, I have been playing a ddr style game on my computer that uses my arrow keys and I think it would be fun to work on a program that would play the game for me with 100% accuracy. I plan on doing this by reading some of the pixels on the screen and holding the correct arrow key until the in game arrow disappears. I guess I'm a bad googler, but I wasn't able to find any information whatsoever. I'm completely comfortable with using many languages, is anyone sure what I'm looking for? [link] [comments]  |

| Posted: 13 Apr 2020 03:59 PM PDT I'm supposed to write an array based off this: ; The name of the array is myArr. Each element is 8 bits and the values are unsigned. ;The value of first element is 10, the value of the second element is 13, the third element is 4. So would the answer be something like this: .data myArr BYTE '10', '13', '4', 0 Use byte since this is 8-bit, and then list the elements? Or do I have to do a list like this: .data myArr BYTE 10 myArr2 BYTE 13, etc? I'm pretty slow when it comes to this. Any help appreciated [link] [comments]  |

| Need help choosing the JS framework / component for creating a timeline based application Posted: 13 Apr 2020 11:10 AM PDT Hi all, as the title said, I need to make a decision what JS framework/library will be used, as well as what timeline component. My requirements (simplified): I need a daily 24 hour timeline component, where I'll plot different team members, working on different projects. Don't want to bore you with business logic, but a usual 'project' lasts for a hour or so. So one employee will work on a few of those in their working time. I would know all the schedule already before making the application, but certain changes might happen 'on-the-fly', like one person might get transferred from a project to project. I need to accommodate that. Drag and drop stuff might not be required but I guess it's nice to have. So, simplified, that's basically it, a bunch of employees (~100) and plot their schedule for today, hour by hour, on which projects their working on. Similar to this: https://zconblog.files.wordpress.com/2017/02/vis-jstimeline.png?w=825 except we don't use trucks, we use people, and different people might be working on same 'orders'. So 1st question: which JS framework to use? I assume the requirements will grow over time so I suppose using some versatile framework will be a help in the future. I was researching React and Vue.JS. Both seem fine, and offer a lot of customization options and possibilities for building a rich-UI web apps. I researched something like Vue vs React (since I know neither), and the finding is that Vue might be a better choice if the requirements are not that huge, and the app itself will be a small, or at the very worst, small-medium scale web application. Do you have any thoughts on this? Regarding the Timeline UI components, I've found google timeline charts and vis.js. Both look nice, but I think visjs offers more when it comes to customizing timeline itself. Again, any thoughts there? Any other libraries I should check out? Since I don't know JS that well, can certain libraries (like vis or google timeline) work with modern frameworks, like vue and react? Thanks for any input. [link] [comments]  |
| Posted: 13 Apr 2020 02:49 PM PDT Hello everyone, I'm happy to learn and try new things. I'm familiar with HTML and CSS on a basic level. I've done some Visual Basic for Applications (Excel) and other simple coding for specific applications. I am wondering if the problem I am trying to solve has already been solved, elsewhere, with slightly different parameters. Our organization uses Windows 365. Here is what I think is going on: there are a lot of divisions in the company, people aren't keeping track of their own publications, and the organization isn't tracking them either, therefore the website is out of date. They'd like more organization and to improve publicity with Tweets when something is published, for example. So far, I've put together an RSS feed to pull together all the publications (the other thing I'm wondering is if there is a way to notify me if someone new is hired (added to the webpage) so that I can update the RSS.). I can also do so for individual authors. The process I'd like to see happen is (bold means I'm not sure how to do this, but I'll take suggestions on all):
The part that I'm struggling with (above) is the drafting/pauses, instead of automatically sending. Potentially, I'd like to do a similar thing for non-publication stuff. For example, using Google, alert me when:
So what would be the best way to get started? Was RSS the right way for the first part? My web searches have turned up several paid options for some of this, but our volume will be so low (only one social media account and probably fewer than three events per week) and I'm not sure they'd cover everything.

| Changes to database not reflected immediately Posted: 13 Apr 2020 06:24 AM PDT Alright so I know this question isn't exactly specific, but that's because I have no idea where to even start or ask. So I thought this reddit may be a good starting point. I have a web-application that uses a MySQL database, and a python back-end to serve pages on requests. This is hosted on a service called "pythonanywhere". It works great, perfectly. The database updates in batches every hour, and i've only just noticed that after the hour I occasionally have to wait a while to see changes reflected in the JSON API I have. Oddly, everything is committed. Firstly let me point out, this isn't a cache issue (at least I think). I hit Ctrl + shift + R in chrome to force it to load but not from the cache. Further, my phone or other browsers won't receive the changes to the database immediately. It's almost like it is reading from the database an hour old, which seems impossible since there is only one database isn't there? be interested to hear the theories and thankyou for any help, or anyone willing to point somewhere else to ask or receive help.

| Best programming practice for web scraping Posted: 13 Apr 2020 02:27 AM PDT Right now, there a lot of delivery services offered by grocery stores but a majority of them aren't able to deliver due to current demands. I wanted to create a tool that allows someone to be notified if a store in their area is accepting deliveries. I've tried figuring out if using some of their public APIs would work but it looks like web scraping is the best course of action. I am adhering to each websites robots.txt to make sure I am not crawling a page that isn't allowed. The main problem is that most of these sites require you to login to an account before you can check for available delivery times. The only option that I appear to have would be to create a dummy account for each site and have it login to check available delivery times for different people's zip codes. But I feel something like that isn't acceptable and wanted to know if anyone had any insight on this / any other ideas. This program will at most be used by a dozen people and I want it to constantly check every few minutes if deliveries are available. Any advice would be appreciated! Thank you! [link] [comments]  |
