coef.PTReg: Extract coefficients from a "PTReg" object

In GEInter: Robust Gene-Environment Interaction Analysis

Extract coefficients from a "PTReg" object

Description

This function extracts main effect and interaction coefficients from a PTReg model, using the stored "PTReg" object.

Usage

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

Arguments

object	Fitted "PTReg" model object.
...	Not used. Other arguments to get coefficients.

Value

The object returned depends on the ... argument which is passed on to the coef method for PTReg objects.

intercept	The intercept estimate.
alpha	The matrix of the coefficients for main environmental effects.
beta	The matrix of the regression coefficients for all main genetic effects (the first row) and interactions.
