Defines the binning to be used in Chi-Sq goodness of fit tests
The Fitting menu Define Chi-Sq Binning command defines the number of bins, type of bins and custom binning to be used for Chi-Sq goodness of fit tests. Bins are the groups that your input data are divided into, similar to the classes used to draw a histogram. Binning can affect the results of Chi-Sq tests and the fit results that are generated. By using the Define Chi-Sq Binning options you can ensure that the Chi-Sq test is using the bins that you deem appropriate. For more information on how the number of bins is used in a Chi-Sq test, see Chapter 2: An Overview of Distribution Fitting.
Note: If you are unsure about the number or type of bins to use for a Chi-Square test, set "Number of Bins" to "Auto" and set "Bin Style" to "Equal Probabilities".
The following entries can be used to define Chi-Sq binning:
