1. ### Beta - Cov(x,y)/Var(x) or SC(x,y)/SS(x)

It's easier to add it at the end. Multiply by 1 which doesn't change anything so it's perfectly acceptable. Keep in mind that n/n = 1
2. ### ARDL package

I highly doubt what you were seeing was a server issue

What do you have for a value
4. ### Conjecture: "SST=SSR+SST does not imply y(x) is an optimal sLR-line" (sLR:=simple Linear Regression)

Ok. That is equivalent to what I would consider the more well known condition of minimizing SSE.
5. ### Regression coefficient interpretation

**** Americans... not realizing that "," is used as the decimal in other countries. :p

I don't quite understand why you're asking here? It's easy enough to just google that. What's the actual issue?
7. ### Conjecture: "SST=SSR+SST does not imply y(x) is an optimal sLR-line" (sLR:=simple Linear Regression)

I think OP needs to define what they mean by 'optimal regression'
8. ### ARDL package

Inf is how R represents "Infinite". An AIC of -Inf means you have a perfect fit to the data.
9. ### Conjecture: "SST=SSR+SST does not imply y(x) is an optimal sLR-line" (sLR:=simple Linear Regression)

I don't understand what you're trying to do with the counterexample approach. Does this help though? https://math.stackexchange.com/questions/709419/prove-sst-ssessr
10. ### Dividing each cell value by its column mean

It cycles through the rows in column 1 first. So if your data is called a and your mean vector is called m it would do a[1,1]/m then a[2,1]/m then a[3,1]/m then a[4,1]/m then recycle the mean vector to give a[5,1]/m. You could use the sweep function to do what you want. > m <-...
11. ### Help with Probability question

Looks good to me
12. ### Beta - Cov(x,y)/Var(x) or SC(x,y)/SS(x)

The good ol "multiply by 1" trick strikes again.
13. ### Those new to R

I mean there are materials for learning base R. You weren't asking about base R. So I directed you to the materials associated with what you were asking about.
14. ### if-condition | Stata beginner needs urgent help

There are no attached files and you didn't actually say what you think the issue is.
15. ### ARDL package

Actually... Haha. I do have an objection to your last post but don't really want to continue down this technical rabbit hole.
16. ### ARDL package

Ackkkktulllyyyyy... It is loaded from a file. Typically lazy loaded and you don't need to specify the absolute path for the data file but... Yeah it's loaded from a file that gets installed when you install the package.
17. ### HELP

This doesn't seem like forum feedback
18. ### Those new to R

Take some time and actually formulate a question.
19. ### Those new to R

I'm not trying to be obtuse... But I literally don't know what your question is here.
20. ### Regression Analysis with Monetary Variables

What does a scatterplot look like if look at something like x against log(y) after removing the 0s from Y. I'm wondering if some sort of 0 inflated model might be useful for you. I personally am not a big fan of the log(x + c) where c is some number (typically 1, sometimes something like .001)...
