Hello,
I come across the following revised multinomial logit model for discrete choice in the literature. It is different from the class logit model which use -mlog- to estimate. How can I estimate the revised version with stata? Thanks in advance

S is the market share (probability) of a product i. p is the price. Alpha is the share weight and Gamma is the logit exponents.
