statsmodels.stats.stattools.jarque_bera(resids, axis=0)[source]

Calculate residual skewness, kurtosis, and do the JB test for normality

Parameters:

resids : array-like

axis : int, optional

Default is 0

Returns:

JB, JBpv, skew, kurtosis :

JB = n/6*(S^2 + (K-3)^2/4) :

JBpv is the Chi^2 two-tail probability value :

skew is the measure of skewness :

kurtosis is the measure of kurtosis :
