eq.hotT2: Hotelling T2

In cribbie/equivalencetests: Equivalence Tests

Description

This function does the one sample Hotelling T2 analog for equivalence tests, determining if a sample's set of means on repeated measures are practically equivalent, given some pre-specified interval in the metric of Mahalanobis distance. The null hypothesis of nonequality among the means of the responses is rejected if the T2 statistic is less than the critical value.

Usage

eq.hotT2(data, repeated, ei, alpha = 0.05)

## S3 method for class 'eq.hotT2'
print(x, ...)

Arguments

data	a data.frame object
repeated	a character vector containing the names of the repeated measures variables
ei	equivalence interval, in the metric of Mahalanobis distance
alpha	alpha/significance level
x	object of class eq.hotT2
...	additional arguments
