Statistical Power calculations for z-test for two independent samples.
currently only uses pooled variance
plot_power ([dep_var, nobs, effect_size, …]) | plot power with number of observations or effect size on x-axis |
power (effect_size, nobs1, alpha[, ratio, …]) | Calculate the power of a z-test for two independent sample |
solve_power ([effect_size, nobs1, alpha, …]) | solve for any one parameter of the power of a two sample z-test |
