Matlab v7 not compatible with FITDIST Function ? Anybody Knows???

Hi all,

Does anybody knows if the function "fitdist" is available for matlab version 7.3.0? When I call for this function it says:

      " Undefined function or method 'fitdist' for input arguments of type 'double'. "

Any help would be appreciated.

Greetings,

FITDIST does not seem to have existed in MATLAB 7.3 (R2006b), but there is an interactive tool called DFITTOOL that helps with Distribution Fitting. Type "doc" to open up the Help Window and navigate to Statistics Toolbox->Probability Distributions->Distribution GUIs->Distribution Fitting Tool for help.

Hi Kaustubha Govind,

It helps a lot, but would be nice to have a function because it's impossible to do this by hand to each one of all my data sets.

You can use the individual, distribution-specific fitting functions (normfit, lognfit, poissfit, etc) or mle

fitdist seems to require the Statistics and Machine Learning Toolbox.
