st: Movestay and error mesage

["Joerg Rocholl" <rocholl@hotmail.com>]

Dear All:

when I use the "movestay" command, I receive the following error message:

"Fitting initial values .....initial vector: copy option requires either a 
matrix or a list of numbers
r(198);"

Is this is a common message? What does it mean? For illustration purposes, I 
slightly revised the example in the help section:

The estimation of

movestay lmo_wage edu13, select(private = m_s1)

works perfectly.

The error message occurs in

movestay lmo_wage edu13, select(private = job_hold)

Do you know of any explanation for this? How can I fix it?

Thank you very much
Jorg
