Thanks Glenn and Maarten. I appreciate it.

Here is part of the "trace" that contains the error:

            - generate double `yb0' = .
            = generate double __000014 = .
            - replace `yb0' = ( `y_bo')^(`alpha') if `y_b0'>=0
            = replace __000014 = ( )^(__00000T) if __000018>=0
invalid syntax
              replace `yb1' = ( `y_b1')^(`alpha') if `y_b1'>=0

I double check the code and nothing seems wrong. Do you have any idea?

Many thanks?

P.S. when I use "ml trace on" , there was message "you must issue -ml
model- first" despite I used  the "ml model" right before that. Any
idea?
