Beta distribution
Posted: Tue Jun 28, 2016 5:44 am
I am trying to estimate the following equation (EViews 7):
where V_Pj and V_Rj are variables and min and max are the minimum and maximum values of V_Rj. a, b, v and w are least squares parameters and Λ(v, w) represents the beta distribution. I tried something using @beta (see below), but couldn't get it right. Any help would be appreciated.

Code: Select all
ls vpj_vrj=c(1)+c(2)*(((vrj-@min(vrj))^(c(3)-1))*((@max(vrj)-vrj)^(c(4)-1))/((@beta(c(3),c(4)))*((@max(vrj)-@min(vrj))^(c(3)+c(4)-1))))
