coef.front41Output: 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.fr

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.
