DescStatUV.test_var()

statsmodels.emplike.descriptive.DescStatUV.test_var

DescStatUV.test_var(sig2_0, return_weights=False) [source]

Returns -2 x log-likelihoog ratio and the p-value for the hypothesized variance

Parameters:	sig2_0 : float Hypothesized variance to be tested return_weights : bool If True, returns the weights that maximize the likelihood of observing sig2_0. Default is False
Returns:	test_results : tuple The log-likelihood ratio and the p_value of sig2_0
