cruder | Generate code for CRUD functions from a Go struct | Generator Utils library

Move the select() before the pivot_wider and everything is fine:

Here are two commands of Java code which will open a window in your instant app to your installable app on Google Play. I translated from Kotlin code I found deep in the sample apps on GitHub here: https://github.com/googlesamples/android-instant-apps.

Kotlin original with Java errors:

This is something between an answer to the question and a continuation of the question. I was kindly referred to another thread where more or less the same question was answered. I didn't follow the answers in that thread very well, being ignorant of the things the people there are talking about, hence the Question: Is what I say below correct? (If yes then this is an answer to the question above; if no I'd appreciate someone explaining why not...)

(i) Since I assign a function to an instance of func instead of to the class, it is now an "instance method", as opposed to a "class method".

(ii) And that's why it's not passed the instance as the first parameter; that happens with class methods but not with instance methods...

I now use GraphQL in conjunction with React instead of using fetch directly, and mostly it works pretty well.

Based on comments from @Josef, the problem is that large numbers don't work with high-order polynomials and statsmodels doesn't auto-scale the domain. In addition, I didn't mention this in the original question because I didn't expect the domain would need to be transformed, but I also needed to predict an out-of-sample value based on the year, so I make this the end of the range:

Using matplotlib.pyplot.legend() before matplotlib.pyplot.show() will solve your problem.

Since you are plotting 3 graphs, and from my understanding you want only 2 labels in the legend, we pass label='_nolegend_' to fit.fittedvalues.plot(). If we do not do so, we will have a 3rd label in the graph legend with a value of None.

Based on comments from @ALollz, when using Patsy notation (e.g. statsmodels.formula.api.ols("y ~ x")), you don't need to include 1 +, as the constant is added by default to the model, although this does not specify that your model has a constant that takes on the value of 1. Instead, it specifies that you have a constant whose magnitude will be given by the intercept coefficient. This is the constant determined by OLS, so it's the one you want.

Indeed, what you try to do is not supported by the XMLWorker architecture. (I'm actually a bit surprised about this; I think I even in some earlier comment here or there claimed it should work.)

The XMLWorker architecture does not allow overlapping usages from the same thread. It does allow overlapping usages from different threads and non-overlapping usages in any threading situation, though.

As your headers and footers appear not to depend on the actual page contents, I'd recommend you switch to a two-pass process: In the first pass create the document body using a Document and a PdfWriter as above, merely without the event listener; in the second pass stamp the headers and footers onto it using a PdfReader and a PdfStamper. Alternatively you can try the work-around posted at the end of this answer.

The XMLWorker keeps a context for the current parsing operation in a Thread Data Slot (in Java in a ThreadLocal).

The contents of the context in the current thread are initialized at the start of XMLParser.ParseWithReader, and the whole context of the current thread is dropped at its end.

The method XMLParser.ParseWithReader eventually is used by each XMLParser.Parse overload and also by each XMLWorkerHelper.parseXHtml overload.

As soon as two parsing attempts using the XMLWorker architecture - e.g. parsing attempts in a page event listener and a parsing attempt filling the body (unless the latter is clearly limited to a single page) - overlap, therefore, they get into each other's way and the attempt finishing first removes the context also used by the other.

There is a work-around for this issue, at least for situations like the one at hand, if one is ok with using reflection and one's runtime environment allows that:

Whenever one switches to another attempt, one can store the current context value and replace it with a value appropriate for the parsing coming up. As context is declared private, this requires reflection.

In the case at hand that would be:
