HowTo derive a correct likelihood-ratio chi-squared statistic from lrm() with a rsc() ?
...prox for the L.R. model? (see function below)
dAIC <- function(fit){
logl <- oos.loglik(fit) # derive -2*logL of the model
k <- 2
edf <- fit$stats[4]
# 'edf' is the equivalent degrees of freedom (i.e., the number of
parameters for usul parametric models) of 'fit'.
lrmAIC <- logl + k*edf
return(lrmAIC)
}
Best regards,
Jan

forecasting multiple regression model
Hi all,
Does anyone have the knowledge to help me identify a package capable of
forecasting a MULTIPLE regression model? i have a model with one one
dependant variable and 4 independant variables. i would like to forecast
confidence intervals for a few steps ahead...(DENSITY forecasting).
PS i can forecast a univariate vector, with package 'forecast', however, i
want one that can do
