VARMAXResults.test_serial_correlation(method, lags=None)
Ljungbox test for no serial correlation of standardized residuals
Null hypothesis is no serial correlation.
Parameters: 


Returns: 
output – An array with 
Return type: 
array 
If the first d
loglikelihood values were burned (i.e. in the specified model, loglikelihood_burn=d
), then this test is calculated ignoring the first d
residuals.
Output is nan for any endogenous variable which has missing values.
