model.frame.gamlss
, model.matrix.gamlss
and terms.gamlss
are the gamlss versions of the generic functions
model.frame
, model.matrix
and terms
respectively.
# S3 method for gamlss
model.frame(formula, what = c("mu", "sigma", "nu", "tau"),
parameter= NULL, ...)
# S3 method for gamlss
terms(x, what = c("mu", "sigma", "nu", "tau"),
parameter= NULL, ...)
# S3 method for gamlss
model.matrix(object, what = c("mu", "sigma", "nu", "tau"),
parameter= NULL, ...)
a model.frame, a model.matrix or terms
a gamlss object
a gamlss object
a gamlss object
for which parameter to extract the model.frame, terms or model.frame
equivalent to what
for extra arguments
