Distfit

Purpose

Chitest for all distributions.

Synopsis

res = distfit(x,options)

Description

This command will perform the chi-squared test for all supported distributions and then present a list of the supported distributions from the most likely parent distribution to the least likely (along with the associated p-values).The default behavior is to display a figure containing the results. This can be disabled using options. NOTE: Some distributions will ignore parts of the sample that are not part of the supported range.

INPUTS

• x = The name of a matrix (column vector) in which the sample data is stored.

OUTPUTS

The return value is a structure with fields:

• dist = names of candidate distributions.
• pval = p-value associated with the test statistic.

Options:

• name : 'options', name indicating that this is an options structure,
• plots : [ 'none' | {'final'} ] governs level of plotting,
