coef.selm: Coefficients of objects created by selm

Description

coef method for classes "selm" and "mselm".

Usage

# S4 method for selm
coef(object, param.type = "CP", ...)
# S4 method for mselm
coef(object, param.type = "CP", vector=TRUE, ...)

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.

vector

a logical value (default is TRUE) which selects a vector or a list format of the retuned value

...

not used, included for compatibility with the generic method

Value
