Extract the number of intercepts from a model
num.intercepts(fit, type=c('fit', 'var', 'coef'))
a model fit object
the default is to return the formal number of intercepts used when fitting
the model. Set type='var'
to return the actual number of
intercepts stored in the var
object, or type='coef'
to
return the actual number in the fitted coefficients. The former will be
less than the number fitted for orm
fits, and the
latter for orm
fits passed through
fit.mult.impute
num.intercepts
returns an integer with the number of intercepts
in the model.
