Estimate Means Pairwise

Provides a table of confidence intervals for all unadjusted pairwise comparisons.

Usage

# S3 method for data.frame
estimateMeansPairwise(frame, conf.level=.95, ...)

# S3 method for formula
estimateMeansPairwise(formula, conf.level=.95, ...)

# S3 method for wsm
estimateMeansPairwise(moments, conf.level=.95, ...)

# S3 method for bsm
estimateMeansPairwise(moments, conf.level=.95, ...)

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

conf.level

confidence level of the interval

Value

The returned frame contains the following components:

Diff

the differences between the pairs of means

SE

the standard error of the differences

df

the degrees of the freedom for the differences

LL

the lower limits of the confidence intervals for the differences

UL

the upper limits of the confidence intervals for the differences
