usage: bgod [-l LAGS] [-h] [--export {csv,json,xlsx}]
Show Breusch-Pagan heteroscedasticity test results.
In statistics, heteroskedasticity (or heteroscedasticity) happens when the standard deviations of a predicted variable, monitored over different values of an independent variable or as related to prior time periods, are non-constant. With heteroskedasticity, the tell-tale sign upon visual inspection of the residual errors is that they will tend to fan out over time. [Source: Investopedia]
optional arguments:
-l LAGS, --lags LAGS The lags for the Breusch-Godfrey test (default: 3)
-h, --help show this help message (default: False)
--export {csv,json,xlsx}

Notes:
[1] Standard Errors assume that the covariance matrix of the errors is correctly specified.
[2] The condition number is large, 1.16e+04. This might indicate that there are
strong multicollinearity or other numerical problems.
