fitted
returns the fitted frontier values from stochastic
frontier models estimated with sfacross
, sfalcmcross
,
or sfaselectioncross
.

Currently ignored. |
In the case of an object of class 'sfacross'
, or
'sfaselectioncross'
, a vector of fitted values is returned.
In the case of an object of class 'sfalcmcross'
, a data frame
containing the fitted values for each class is returned where each variable
ends with '_c#'
, '#'
being the class number.
The fitted values are ordered in the same way as the corresponding observations in the dataset used for the estimation.
sfacross
, for the stochastic frontier analysis model
fitting function using cross-sectional or pooled data.
sfalcmcross
, for the latent class stochastic frontier analysis
model fitting function using cross-sectional or pooled data.
sfaselectioncross
for sample selection in stochastic frontier
model fitting function using cross-sectional or pooled data.
