Rayleigh Distribution Function Code.

[AMD123]

Dear ImageJ Community,

I would like to fit my data ( using Curve Fitter on ImageJ) to a Rayleigh Distribution function. Does anyone have a Syntax for this function?

Thank you,

[Peter Haub]

Hello AMD123

the user-defined function for the Rayleigh distribution in the Curve
Fitter is

y = x/(a*a) * exp(-x*x/2/(a*a))

where a is the parameter to estimate.

Regards,
Peter

Thank you Peter!

I will use the built-in Macro:
Fit.doFit(equation, xpoints, ypoints)- Fits the specified equation to the points defined by xpoints, ypoints.

I will use the equation you provided, but I'm not sure about the appropriate values for X and Y !!

Thank you,
