coef.front41Output {frontier}R Documentation

Coefficients from Frontier 4.1

Description

These methods return the coefficients and their covariance matrix from a model estimated by Frontier 4.1.

Usage

   ## S3 method for class 'front41Output':
   coef( object, which = "MLE", ... )

   ## S3 method for class 'summary.front41Output':
   coef( object, which = "MLE", ... )

   ## S3 method for class 'front41Output':
   vcov( object, ... )

Arguments

object an object of class front41Output or summary.front41Output (read/created by front41ReadOutput or summary.front41Output, respectively).
which character string indication, which coefficients should be returned: either 'OLS' (from OLS estimation), 'GRID' (from grid search), or 'MLE' (from maximum likelihood estimation).
... currently ignored.

Value

The coef method applied to an object of class front41Output returns a vector containing all coefficients estimated by Frontier 4.1.
The coef method applied to an object of class summary.front41Output returns a matrix containing the estimates, their standard errors, the t values and P values of all coefficients estimated by Frontier 4.1.
The vcov method returns the covariance matrix of all coefficients estimated by Frontier 4.1.
