I saw a thread with the above subject line concerning
piecewise linear regression posted in 2005 on Statalist.
I am facing the same problem now; that of estimating the unknown
change point. Mention was made of using -nl- but it uses
least squares method. The only way to solve this problem
is numerical optimization. The problem can be solved
quite easily in SAS using NLIN PROC.
Is there a Stata solution?
