pdiff: Table of p-values for Differences of Least Squares Means

In byandell/pda: Practial Data Analysis for Designed Experiments

Description

Takes the fit of a linear model, extracts the least squares means and their standard errors, and the residual DF, and constructs the p-values for all pairwise comparisons.

Usage

pdiff(fit, lsm=lsmean(fit), pred, se, rdf=df.resid(fit))

Arguments

fit	object from linear model fit
lsm	least squares means object from lsmean
pred	outer difference of least squares means
se	SE for differences in pred
rdf	residual degrees of freedom from model fit

Value

Square matrix of size length( pred ) sorted from largest to smallest pred with p-values as entries. Diagonal entries are all 1. Row and column names are levels of pred.
