summary.front41Output summarizes the estimation results
of a model estimated by Frontier 4.1..
## S3 method for class 'front41Output': summary( object, ... ) ## S3 method for class 'summary.front41Output': print( x, efficiencies = FALSE, ... )
object |
an object of class front41Output
(read/created by front41ReadOutput. |
x |
object of class summary.front41Output
(returned by the summary method for objects of class
front41ReadOutput). |
efficiencies |
logical. Print all efficiency estimates?
(If FALSE, only the mean efficiency is printed.) |
... |
currently ignored. |
The summary method returns a list of class
summary.front41Output
with the same elements as object returned by front41ReadOutput.
However, the elements olsResults, gridResults, and
mleResults have an additional culumn with marginal significance
levels (P values).
The P values of the OLS estimates are calculated using
the t distribution,
while the (asymptotic) P values of the ML estimates
are calculated based on the assumption
that their t values follow an (asymptotic) standard normal
distribution.
