Test Means Complex

Provides the statistical significance tests for mean contrasts and the difference between those contrasts.

Usage

# S3 method for data.frame
testMeansComplex(frame, contrast1, contrast2, main=NULL, labels=NULL, digits=3)

# S3 method for formula
testMeansComplex(formula, contrast1, contrast2, main=NULL, labels=NULL, digits=3)

# S3 method for wsm
testMeansComplex(moments, corrs, contrast1, contrast2, main=NULL, labels=NULL, digits=3)

# S3 method for bsm
testMeansComplex(moments, contrast1, contrast2, main=NULL, labels=NULL, digits=3)

Arguments

frame

a set of (non-empty) numeric vectors of data values

formula

a formula of the form lhs ~ rhs where lhs is a numeric variable giving the data values and rhs a factor giving the corresponding groups

moments

a matrix/frame of descriptive/summary statistics

corrs

a matrix/frame of correlations among the measures

contrast1

a vector of codes for the first contrast among all means

contrast2

a vector of codes for the second contrast among all means

labels

custom labels for the contrasts

Value

The returned frame contains the following components:

Est

the contrasts for the variables or groups and the difference

SE

the standard errors of the contrasts for the variables or groups and the difference

df

the degrees of freedom for the contrasts of the variables or groups and the difference

t

the t values for the contrasts and the difference

p

the p values for the contrasts and the difference
