e1: Get a Contrast Matrix for Type I SS
In sasLM: 'SAS' Linear Model
e1 R Documentation
Get a Contrast Matrix for Type I SS
Description
Makes a contrast matrix for type I SS using forward Doolittle method.
Usage
e1(XpX, eps=1e-8)
Arguments
XpX
crossprodut of a design or model matrix. This should have appropriate column names.
eps
Less than this value is considered as zero.
Details
It makes a contrast matrix for type I SS. If zapsmall is used, the result becomes more inaccurate.
Value
A contrast matrix for type I SS.
Author(s)

Examples
x = ModelMatrix(uptake ~ Plant + Type + Treatment + conc, CO2)
round(e1(crossprod(x$X)), 12)
