Value
- The
coef method returns an object of class coef.aidsEst
containing following objects: - alpha0a scalar, coefficient alpha0
(only for the AIDS with translog price index).
- alphaa vector of the alpha coefficients.
- betaa vector of the beta coefficients.
- gammaa matrix of the gamma coefficients.
- deltaa matrix of the delta coefficients
(only if the model was estimated with demand shifters).
