Hi Peppe,

not that I know of... I was thinking there could be something related to colors theming - but I don't think so with respect to the type you want i even doubt that jmath has. I used only "counts" (like for histograms); which is a bit different - or? But you could also check if Sextante has something?

For OJ source code you could just run a text search using "frequency"

cheers,

Stefan

Hi Peppe,

I think that OpenJUMP plugins including statistical functions make use of jmatharray-20070905. It does not include so many functions, but it is very lightweight.
Maybe Stefan knows a bit more about it.

Maybe there are some other places where statistical functions have been coded. Do cou need it for feature attribute analysis or for image analysis ?

Hi all,
do we have calsses/methods in OJ core to calculate frequencies (absolute, relative and cumulative) of an array of numbers? I can implement these methods but I would prefer to use something already in the OJ source.
thanks
Peppe
