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.
