Distribution Fitting

    

  1. Select Continuous or Discrete. Continuous distributions will use the Anderson Darling goodness of fit statistic, and if practically possible, a p-value. Discrete distributions will use the Chi-Square goodness of fit statistic and p-value.
  2. Select All Distributions or Automatic Best Fit. Automatic Best Fit will return the distribution with the lowest Anderson-Darling or Chi-Square statistic.
  3. See Appendix: Distribution Fitting - Maximum Likelihood Estimation of Parameters for further details on parameter estimation.
  4. If distribution fitting has been performed, the Select Stored Distribution Fit option will become available in the Input Distribution dialog for selection of variable name(s) and stored distribution(s). The input distribution parameter values will automatically be populated.
