(dictionary) Dictionary including all attributes from the SARIMAX model instance. If a number is given, the confidence intervals for the given level are returned. This class functions mainly as a container for t_test, f_test and wald_test for the parameters of a model. These values are substituted in the original equation and the regression line is plotted using matplotlib. The p-value correction is generic and based only on the p-values, and does not take any special structure of the hypotheses into account.
