class statsmodels.stats.power.TTestIndPower(**kwds) [source]

Statistical Power calculations for t-test for two independent sample

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 t-test for two independent sample
solve_power([effect_size, nobs1, alpha, …]) solve for any one parameter of the power of a two sample t-test
