PRMap: Analytical power calculation for PRM design problem

In baolinwu/SPprm: Statistical methods with power calculation for paired repeated measures comparisons: application to pulse oximetry studies

Description

Due to its nature of composite null hypothesis, it is not trivial to derive the analytical power calculation. We develop an average log likelihood based approach to quickly compute the power.

Usage

PRMap(alpha = 0.05, n, m, s2w, s2b, mu, rho, REML = TRUE)

Arguments

alpha	desired significance level. Default to 0.05
n	number of subjects
m	number of repeated measures for each subject
s2w	within subject variation
s2b	between subject variation
mu	mean measure difference
rho	null threshold of acceptable RMS value
REML	using REML instead of MLE. Default to TRUE.

Value

xq

computed quantile for the QMS test statistic

size

computed actual type I error

pwr

computed power

par0

estimated null parameter values
