Distribution Fitting Options

The SPAApplication.FitOptions property allows to specify various options affecting the distribution fitting process.

Domain Bounds

The lower/upper domain bound settings let you control what distribution types will be automatically fitted to your data. For details, please refer to the Domain Bounds topic.

MLE Options

Many distributions supported by the SPA SDK are fitted using the MLE (Maximum Likelihood Estimates) method. For most of them, the iterative parameter estimation algorithm is used. The SDK provides a way to specify the maximum number of iterations (SPAApplication.FitOptions.MLMaxIterations) and the accuracy of the estimation (SPAApplication.FitOptions.MLAccuracy) affecting the behaviour of this algorithm.

Goodness of Fit Options

The SPAApplication.FitOptions.GofEnabled property lets you specify the goodness of fit tests that should be performed after the distributions are fitted.

To control how the fitted distributions are ranked (sorted), use the SPAApplication.FitOptions.RankBy property.
