    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

    I highly doubt what you were seeing was a server issue

    Please check your Kolmogorov-Smirnov table for me?

    What do you have for a value

    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.

    Regression coefficient interpretation

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

    Please check your Kolmogorov-Smirnov table for me?

    I don't quite understand why you're asking here? It's easy enough to just google that. What's the actual issue?

    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'

    Inf is how R represents "Infinite". An AIC of -Inf means you have a perfect fit to the data.

    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

    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[1] then a[2,1]/m[2] then a[3,1]/m[3] then a[4,1]/m[4] then recycle the mean vector to give a[5,1]/m[1]. You could use the sweep function to do what you want. > m <-...

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

    The good ol "multiply by 1" trick strikes again.

    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.

    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.

    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.

    Take some time and actually formulate a question.

    I'm not trying to be obtuse... But I literally don't know what your question is here.

    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)...
