coef: Extract coefficients from smsn.lmm and smn.lmm objects

In skewlmm: Scale Mixture of Skew-Normal Linear Mixed Models

Extract coefficients from smsn.lmm and smn.lmm objects

Description

It extracts estimated coefficients from smsn.lmm and smn.lmm objects. The estimated coefficients are obtained by adding together the fixed and random effects estimates.

Usage

## S3 method for class 'SMN'
coef(object, ...)
## S3 method for class 'SMSN'
coef(object, ...)

Arguments

object	An object inheriting from class SMN or SMSN, representing a fitted scale mixture skew-normal linear mixed model.
...	Additional arguments

Value

Matrix of coefficients.
