plot_diagnostics(variable=0, lags=10, fig=None, figsize=None, truncate_endog_names=24)¶
Diagnostic plots for standardized residuals of one endogenous variable
Index of the endogenous variable for which the diagnostic plots should be created. Default is 0.
Number of lags to include in the correlogram. Default is 10.
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().
If a figure is created, this argument allows specifying a size. The tuple is (width, height).
Figure instance with diagnostic plots
Produces a 2x2 plot grid with the following plots (ordered clockwise from top left):
Standardized residuals over time
Histogram plus estimated density of standardized residuals, along with a Normal(0,1) density plotted for reference.
Normal Q-Q plot, with Normal reference line.
