Master thesis

[Florian Frankl]

Good day everyone!

I am currently writing my master thesis and for the first time I am using Stata to analyze a data set.
The background information on the individual variables and the foreach loop are secondary for now. My big problem is the following: Stata creates a matrix with all variables I want to have. However, the results are not saved in my desired file path. Every time I try to save something, the destination remains empty. What am I doing wrong?
Thank you in advance.

You have the syntax all wrong in your -matsave- command. It should be -matsave- followed by the name of the file you want to save them in, followed by the name of the matrix. And there should be no commas separating those.
