Hi everybody

I need to model the decision on how much to buy (continuous decision) given
the choice of the brand (discrete decision), as in Krishnamurthi & Raj "A
model of brand choice and purchase quantity price sensitivities". Marketing
Science, vol. 7 n. 1 Winter 1988.

This model is called "limited dependent variable with selectivity", as also
explained in:
Lee, LF (1983). "Generalized econometric models with selectivity,"
Econometrica 51 (March), 507-512.

I would like to know whether there is a routine in SAS.

Thanks a lot
