rmat {dwp}

Simple Utility Function Used in Optimizing the GLM

Description

A simple utility function that is used in fitting a GLM, creating a matrix of "x" values for use in the polynomial part of a xep-type model.

Usage

rmat(r, distr)

Arguments

r

vector of distances (>=0)

distr

name of the distribution

Value

array with length(r) rows and p columns, where p is the number of parameters in the glm (including the intercept). The first column is all 1s, and the remaining columns are functions of r, specifically, log(r), r, r^2, r^3, or 1/r, depending on what the distribution requires.
