UNIVARIATE Procedure Enhancements

  • The HISTOGRAM statement now supports the OVERLAY option, which overlays histograms that are associated with different levels of a CLASS variable onto a single plot.

  • Maximum likelihood estimation for Johnson $S_ U$ distribution parameters has been improved. You can fit a Johnson $S_ U$ distribution by specifying the SU option in the HISTOGRAM statement. You can request maximum likelihood estimation by specifying the FITMETHOD=MLE suboption, and you can control the optimizer that performs the estimation by specifying the new OPTBOUNDRANGE=, OPTMAXITER=, OPTMAXSTARTS=, OPTPRINT, OPTSEED=, and OPTTOLERANCE= suboptions.
