Struct NormalIndPower 

pub struct NormalIndPower;

Power of a two-sample z-test for independent samples (normal approximation).

effect_size is the standardized mean difference, nobs1 the size of the first sample, and ratio the size of sample two relative to sample one (nobs2 = ratio·nobs1; ratio = 0 gives the one-sample test). Mirrors the reference NormalIndPower with ddof = 0.

Implementations

impl NormalIndPower

pub fn power( &self, effect_size: f64, nobs1: f64, alpha: f64, ratio: f64, alternative: Alternative, ) -> f64

Power at the given configuration.

pub fn solve_power( &self, effect_size: f64, alpha: f64, power: f64, ratio: f64, alternative: Alternative, ) -> f64

Solve for nobs1 achieving power at the given configuration.
