Recalibration of constants

Dear all,

does anyone know a convenient way to recalibrate ASCs according outside market shares (see Train, p 33)? I see no way to manipulate the $estimate in an apollo_estimate() object.

Hi Sven

you can easily change model$estimate.

E.g. use

model$estimate["asc_1"]=model$estimate["asc_1"]+log(real_demand/model_demand)
