Hello,

If I want c#2 to be my stayer class, do I do this:

%c#2%
c2#1 ON c1#1@20;

OR this:

%c#2%
c2#1 ON c1#1@-20;

(I thought that more negative logit thresholds = higher probability, such that a -20 logit threshold transition from class 1 time 1 to class 1 time 2 would indicate that the probability of transitioning from class 1 time 1 to
class 2 time 2 is ONE)?

thank you

Sorry I meant "a -20 logit threshold transition from class 1 time 1 to class 1 time 2 would indicate that the probability of going from CLASS 1 TIME 1 to CLASS 1 TIME 2 is ONE)?

The c2# on c1# language refers to logistic regression terms described in chapter 13 of the UG. These are in logit scale, not threshold scale, so signs should not be reversed. +20 is a high logit and therefore a high probability. The threshold parameterization is only for observed categorical variables in order to cover ordinal variables (thresholds are ordered).
