Diagnostic plots for standardized residuals

Parameters:

lagsint, optional

Number of lags to include in the correlogram. Default is 10.

figFigure, optional

If given, subplots are created in this figure instead of in a new figure. Note that the 2x2 grid will be created in the provided figure using fig.add_subplot().
