            R: Trying to recreate mean-median difference gerrymander tests
            Asked 2022-Feb-09 at 23:58

            I'm trying to recreate the mean-median difference test described here: Archive of NYT article. I've downloaded House data from MIT's Election Lab, and pared it down to the 2012 Pennsylvania race. Using dplyr, I whittled it down to the relevant columns, and it now looks something like this:

            Answered 2022-Feb-09 at 23:58

            I figured it out! Randomly placing voters in each district is not correct, and honestly it was pretty silly of me to do so. Instead, I had to use dplyr to create a data frame with the number of Democrat and Republican votes in each of the 435 House districts, one district per row. Then, I followed the advice on page 12 of this paper. I created samples of 18 districts sampled from this 435-row data frame, rejecting them if the mean vote share was more than 1 percent away from that of PA. The results have a much nicer 95% confidence interval, that matches the results of the original article.

            For a header cell with sorting enabled, the DataControlField will add a LinkButton to the TableCell, and set its properties accordingly.

            When you set the TableCell's Text property, it removes all of the controls which were created by the DataControlField. This includes the LinkButton used to sort the cell.

            You need to change the text of the LinkButton instead.

            The problem is you aren't going to be able to keep all the Docs (spaCy output) in memory at the same time, so you can't just put the output in a column of a dataframe. Also note this is not a spaCy issue, this is a programming issue.

            You need to write a for loop and put your processing in it:

            Python yFInance api how to get close share price instead of adjusted close share price?
            Asked 2021-Sep-16 at 09:01

            I am trying to get closing share price from yFinance API for Devon DVN. The problem is that the API gives adjusted closing share price as closing share price in the response data which can sometimes be different.

            As seen in yahoo finance, DVN closing share price for 9th Sept 2021 was 28.45, and adjusted closing share price was 27.96

            In API response from yFinance I get the closing share price as 27.96 which should be the adjusted value, not the closing value.

            Now how do I get the closing share price from yFinance instead of adjusted share price?

            Your code is correct with a (small minor) problem: your pivot refuses to work because of a duplication of a symbol (with the same dates).

            Check list_2014 - you have 'INFO' twice. Simply remove one and re-run.

            how to wget or curl from a download button with no attached content URL?
            Asked 2020-Oct-05 at 15:23

            I'm trying to download some files from the ICEWS dataset at https://dataverse.harvard.edu/dataverse/icews. I'm trying to do it on a Google VM instance because I am on a slow connection with data limits that are expensive to break. I have tried both curl and wget without success. For any given file I'd like to download, there is a download button with a URL attached to it, for example:

            http://dataverse.harvard.edu/file.xhtml?persistentId=doi:10.7910/DVN/28075/K7L9Y8#

            But this URL appears to only be a link to the location of the button on the current page. Using this URL with either wget or curl results in the download of the HTML of the current page rather than the download of the file content. I can find no direct link to the content itself, and also cannot find a way to print out the redirect chain that results in clicking the download button.

            What is a good solution to this problem? Command-line would be preferred, but if there is some GCP specific workaround, that would be good too. I'm a bit of a newb at both, so simple is better.
