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,
Examples
distfit(x)
