scripts default iconcauchy (Scripts) Publisher's description

Cauchy cdf, pdf, inverse cdf, parameter fit, and random generator.

Cauchy cdf, pdf, inverse cdf, parameter fit, and random generator.

Implementation package of the Cauchy distribution.

cauchycdf: Cauchy cumulative distribution function (cdf).
cauchyfit: Parameter estimation for Cauchy data.
cauchyinv: Inverse of the Cauchy cumulative distribution function (cdf).
cauchypdf: Cauchy probability density function (pdf).
cauchyrnd: Generate random numbers from the Cauchy distribution.

If you find any errors, please let me know (peder at axensten dot se).

NOTE: I'd like to know about the math for calculating the parameters confidence interval in cauchyfit. Any help appreciated.

Should work on almost any version of Matlab.

Version 1.0, 2006-07-10.
Version 1.1, 2006-07-26.
- Added cauchyfit to the cauchy package.
Version 1.2, 2006-08-06:
- cauchyinv(0, ...) returned a large negative number but should be -Inf.
- Can now estimate one parameter when the other is given.
- Size comparison in argument check didn't work.
- Various other improvements to check list.
- The arrangement of arguments now follows the ways of Statistics Toolbox.
- Put the actual mle in a separate file.

System Requirements:

MATLAB 7.0.1 (R14SP1)
Program Release Status: New Release
Program Install Support: Install and Uninstall
