pair_prop_size: Sample Size or Power for Paired-Sample Proportion Test

Description

Calculates sample size or power for a paired-sample proportion test.

Usage

pair_prop_size(p01, p10, alpha, beta = NULL, n = NULL, test_type = "2-side")

Value

Numeric. Returns sample size (if beta is given), or power (if n is given).

Arguments

p01

Numeric. Proportion of discordant pairs with (before = 1, after = 0).

p10

Numeric. Proportion of discordant pairs with (before = 0, after = 1).

alpha

Numeric. Type I error rate.

beta

Numeric (optional). Type II error rate. Required for sample size calculation.

n

Integer (optional). Sample size. Required for power calculation.

test_type

Character. "2-side" or "1-side". Default is "2-side".

Examples

# Sample size for `"2-side"` test
pair_prop_size(p01 = 0.45, p10 = 0.05,
               alpha = 0.1, beta = 0.1, test_type = "2-side")

# Power of `"2-side"` test
pair_prop_size(p01 = 0.45, p10 = 0.05,
               alpha = 0.1, n = 23, test_type = "2-side")

# Sample size for `"1-side"` test
pair_prop_size(p01 = 0.45, p10 = 0.05,
               alpha = 0.05, beta = 0.1, test_type = "1-side")

# Power of `"1-side"` test
pair_prop_size(p01 = 0.45, p10 = 0.05,
               alpha = 0.05, n = 23, test_type = "1-side")
