Sample Size Tables for the 2x4x4 Replicate Crossover Design

Description

These data.frames give sample size tables calculated with sampleN.TOST() for the 2×4×4 replicate crossover design (2-treatment 4-sequence 4-period design).

Details

The data.frames can be accessed by their names.

data.frame	Description
ct9.6.4	Additive model, theta1=--0.2, theta2=+0.2 (BE limits 0.80 -- 1.20)
	approximate power via shifted non-central t-distribution
ct9.6.8	Multiplicative model, theta1=0.8, theta2=1.25 (1/theta1)
	approximate power via shifted non-central t-distribution

Attention! CV is se (standard error) of residuals.

Note

Scripts for creation of these data.frames can be found in the /tests sub-directory of the package.
Comparing the results of these scripts to the corresponding data.frames can be used for validation purposes.
