In lrstat: Power and Sample Size Calculation for Non-Proportional Hazards and Beyond

Power for Poisson One-Sample Exact Test

Description

Obtains the power for Poisson one-sample exact test.

Usage

powerOneRateExact(
  n = NA_integer_,
  lambdaH0 = NA_real_,
  lambda = NA_real_,
  D = 1,
  alpha = 0.025
)

Arguments

n	The sample size.
lambdaH0	The Poisson rate under the null hypothesis.
lambda	The Poisson rate under the alternative hypothesis.
D	The average exposure per subject.
alpha	The one-sided significance level. Defaults to 0.025.

Value

A data frame containing the critical value of the number of events for rejecting the null hypothesis, the attained type I error, the power for the exact test, the sample size, the Poisson rates under the null and alternative hypotheses, the average exposure, and the direction of the alternative.
