Extract fitted frontier values of classic or latent class stochastic models
## S3 method for class 'sfacross' fitted(object, ...) ## S3 method for class 'lcmcross' fitted(object, ...)
In the case of an object of class 'sfacross', a vector of fitted values is returned.
In the case of an object of class 'lcmcross', a data frame containing the
fitted values for each class is returned where each variable terminates 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.
lcmcross, for the latent class stochastic frontier analysis
model fitting function.
