coef.aidsEst function

Coefficients of an Almost Ideal Demand System

These methods return and print the coefficients from an Almost Ideal Demand System.

## S3 method for class 'aidsEst'
coef( object, ... )

   ## S3 method for class 'coef.aidsEst'
print( x, ... )

Arguments

• object: an object of class aidsEst.
• x: an object of class coef.aidsEst.
• ...: further arguments for methods

Returns

The coef method returns an object of class coef.aidsEst

containing following objects: - alpha0: a scalar, coefficient alpha0 (only for the AIDS with translog price index).

• alpha: a vector of the alpha coefficients.

• beta: a vector of the beta coefficients.

• gamma: a matrix of the gamma coefficients.

• delta: a matrix of the delta coefficients (only if the model was estimated with demand shifters).
