thanks Trubador!

Does it happen all the time? What if the data don't have those values?

And does it still recognize as "NA" if I input zero instead of NA?

Thanks again!

Hello,

Could someone help me please? I uploaded the files. Error: "Near Singular Matrix in "Do_ghc.ls Y C (@trend>35-2) G"
This error occurs when I run the program under the regime shift.

thanks in advance!
