Hello,
I have an issue with running a linear regression analysis.
I have a dependent variable (ordinal scale, 1-2) and three independent variables (interval scale, 1-8) and coded and defined missing values as "99".
Whenever I am adding a second covariate to the model I am receiving the error message "0 (non-NA) cases".
When trying to run logistic regression it says "Variable 1 has no levels" (screenshot attached).
Did anyone experience the same issue and know how to solve it?
Many thanks in advance for your help!

Re: Error message "0 (non-NA) cases" linear regression
this usually means that there are no or few combinations of 'Low info-sharing', 'No policy' and 'Short policy' where there aren't missing values.

Hello Jonathan,
Thanks for the explanation.
I've identified the error and computed a new variable.
