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.
