Re: st: -flex- (Flexible PML estimation of models for doubly-bounded data) is now available from SSC

["Santos Silva, J.M.C." <jmcss@essex.ac.uk>]

Dear Rich,

Thank you very much for your interest in our work. As I said in my original post,
-flex- generalizes the logit specification; in particular it allows for a rich pattern 
of asymmetric link functions. One of the references in the help file contains an 
application where this generalization makes a big difference. 

Please do not hesitate to contact me if you have any further questions on this.

With best regards,

Joao
