Estimate Means Complex

Provides the confidence intervals for mean contrasts and the difference between those contrasts.

Usage

# S3 method for data.frame
estimateMeansComplex(frame, contrast1, contrast2, conf.level=.95, labels=NULL)

# S3 method for formula
estimateMeansComplex(formula, contrast1, contrast2, conf.level=.95, labels=NULL)

# S3 method for wsm
estimateMeansComplex(moments, corrs, contrast1, contrast2, conf.level=.95, labels=NULL)

# S3 method for bsm
estimateMeansComplex(moments, contrast1, contrast2, conf.level=.95, labels=NULL)

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

conf.level

confidence level of the interval

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

LL

the lower limit of the confidence intervals of the contrasts and the difference

UL

the upper limit of the confidence intervals of the contrasts and the difference
