residuals.selm: Residuals and fitted values from selm fits

Description

residuals and fitted methods for classes "selm" and "mselm".

Usage

## S3 method for class 'selm':
residuals(object, param.type = "CP", ...)
## S3 method for class 'mselm':
residuals(object, param.type = "CP", ...)
## S3 method for class 'selm':
fitted(object, param.type = "CP", ...)
## S3 method for class 'mselm':
fitted(object, param.type = "CP", ...)

Arguments

object

an object of class "selm" or "mselm" as created by a call to function selm.

param.type

a character string which indicates the required type of parameter type; possible values are "CP" (default), "DP", "pseudo-CP" and their equivalent lower-case expressions.

...

not used, included for compatibility with the generic method

Value

• a numeric vector (for selm-class objects) or a matrix (for mselm-class objects)
