Hi, i have a problem i am trying to make linear regression on R with lm.
The problem is that for example when i do:
It gives me at results:
Coefficients: PsyT58,PsyT59,PsyT60,PsyT61,... with all the values of PsyT
I don't understand why, it should give me just 2 coefficients Intercept and PsyT.
Some values of PsyT was missing and replaced by a '.' but i filtered it and the problem is still here.
Please if you have an answer i would like to know it thank you :)!
