Hello,
I'm trying to calculate the dfiference of certain Times on the basis of a mixed-effect linear regression model.
The model output looks like the following:
Array
The consecutive margins output is then giving me this:
Array
Well,since we clearly know, that there aren't any data for Saentis == 0 and Time == 4
the linear combination of (lincom 0#15 - 0#4) should result in an error.
But the output gives me an unclear output.
Array

For your help, I am very grateful.
Best regards, Simon
