powerOneRateExact {lrstat}

Power for Poisson one-sample exact test

Description

Obtains the power for Poisson one-sample exact test.

Usage

powerOneRateExact(
  n = NA_real_,
  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.
