Just -replay- via

seqlogit, coefl

and you see all the necessary names to talk to the coefficients:

Betreff: st: Storing coefficients after seqlogit

Dear list, 

how can I access and store the coefficients after -seqlogit- separately
by transition level? For instance, using the -seqlogit- help file
example, after having performed -seqlogit-, I could write 

    scalar s1 = _b[white],

but this gives my only the estimate of "white" for the first transition.
How can I get scalars for the estimates of the other levels?

Thanks for any suggestions!
Dominik
