eq.1way.ww: Wellek-Welch equivalence test for k-groups

In cribbie/equivalencetests: Equivalence Tests

Description

This function computes the Wellek-Welch equivalence test for k-groups. This addresses the research question about equivalence for means among k independent groups. The Welch adjustment provides a robust correction for unequal vairances among the k groups.

Usage

eq.1way.ww(dv, group, eps, alpha = 0.05)

## S3 method for class 'eq.1way.ww'
print(x, ...)

Arguments

dv	a numeric vector for the continous dependent variable
group	grouping variable that can be coerced to a factor
eps	numeric value defining the size of the equivalance interval
alpha	the appropriate alpha level
x	object of class eq.1way.ww
...	additional arguments
