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.
