Statistical Power calculations for z-test for two independent samples.
currently only uses pooled variance
Methods
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 t-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 |
