Power Calculation for Difference of Means (DOM) Hypothesis Test

Computes the statistical power for testing the difference of means (DOM) between two groups using Monte Carlo simulations. The power is estimated based on specified sample sizes, means, standard deviations, and significance level.

Arguments

seed

Integer. Seed for reproducibility.

mu_test

Numeric. Mean of the test group.

mu_control

Numeric. Mean of the control group.

sigma_test

Numeric. Standard deviation of the test group.

sigma_control

Numeric. Standard deviation of the control group.

N_test

Integer. Sample size of the test group.

N_control

Integer. Sample size of the control group.

lb

Numeric. Lower bound for the equivalence margin.

ub

Numeric. Upper bound for the equivalence margin.

alpha

Numeric. Significance level (default = 0.05).

nsim

Integer. Number of simulations (default = 10,000).

Value

Numeric. Estimated power (probability between 0 and 1).
