fitted.gamlss: Extract Fitted Values For A GAMLSS Model

Description Usage Arguments Value Author(s) References See Also Examples

Description

fitted.gamlss is the GAMLSS specific method for the generic function fitted which extracts fitted values for a specified parameter from a GAMLSS objects. fitted.values is an alias for it. The function fv() is similar to fitted.gamlls() but allows the argument what not to be character
