Extract the Coefficient by Type

Description

Extract specific types of coefficient from a lvm object: covariance coefficient(s) (coefCov), extra parameter(s) (coefExtra), position in the list of models for each coefficient (coefIndexModel), intercept coefficient(s) (coefIntercept), coefficient(s) that are used as reference (coefRef), regression coefficient(s) (coefReg), variance coefficient(s) (coefVar).

Arguments

object

a lvm model or a fitted lvm model

value

should the name of the coefficient be returned? Else return the coefficients

keep.var

should the variance coefficients be returned?

...

arguments to be passed to

Value

A vector containing the names of the positions of the coefficients.
