st: nl estimation with repeated data

[VIVIAND Xavier <Xavier.Viviand@mail.ap-hm.fr>]

Dear StataList,


I would like to fit an Emax model (E0-((Emax.C^n)/(EC50^n+C^n)) where
several data are available for each patient.
Unfortunately, the nl procedure does not include a cluster option.
Does someone know how to do it ?
Sincerely yours,

Xavier VIVIAND
