an object of class coef.aidsEst.
further arguments for methods
The coef method returns an object of class coef.aidsEst
containing following objects:
a scalar, coefficient alpha0 (only for the AIDS with translog price index).
a vector of the alpha coefficients.
a vector of the beta coefficients.
a matrix of the gamma coefficients.
a matrix of the delta coefficients (only if the model was estimated with demand shifters).
