coef.front41Output {frontier} | R Documentation |
These methods return the coefficients and their covariance matrix from a model estimated by Frontier 4.1.
## 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, ... )
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. |
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.
