Probability Distribution Plot Options

Display

Specifies the output to be displayed.

Parameters	Displays the fitted parameters of the specified distribution, and some sample statistics of the observed data.
Distributional Tests	Displays results from 3 empirical tests (the Anderson-Darling, Cramer-von Mises and Watson statistics), that test how well the observed cumulative probability density (cdf) fits the theoretical cdf.

Estimate Constant

Some distributions (Log-Normal, Gamma, Weibull, Beta type 1, Beta type 2 and Pareto) can have an extra parameter (a) estimated, so that X-a follows the specified distribution. Selecting this option will estimate a value for a.

Display Difference from Expected

Selecting this option plots the difference between the data and the expected values, so that departures can be observed more easily in a horizontal direction rather than on a 45 degree slant.

Display Reference Line

When plotting the data against the expected values, selecting this option allows the 1-1 line to be added to the graph, so that departures from this can be more easily observed.

Display Graph in Output Window

This option can be used to plot a character based graph in the output window rather than in the default high resolution graphics window.
