fuzzy kappa
Dear List and Andrey and Paulo You might like to look at the Fuzme package at this link http://smartdigiag.com/software/#s-4. The notes on it say: /Fuzme is an R package for calculation of Fuzzy k-means with/without extragrades. I wanted to integrate fuzzy-k means into my R workflow so i translated some of Budiman Minansy?s matlab code into R. The R version of Fuzzy k-means with extragrades is a little buggy. The FuzME <http://sydney.edu.au/agriculture/pal/software/fuzme.shtml> software is more stable and efficient. I would recommend using that for most things. If you are trying to embed the classification into your R workflow though, the R packages is OK, but not as computationally efficient. I am working on it when i can./ regards David

Hi Andrey and Paulo I reached out to the author of ithir package for his current advice. He may respond here if time permits. cheers David ?Sent from TypeApp ? On 24 Nov. 2021, 21:10, at 21:10, Paulo Flores Ribeiro<paulo.flores.mail at gmail.com> wrote:
Thank you Andrey, I peeked at the goofcat and saw that it has a function to calculate kappa, but it seems to be just "normal" kappa (in the sense of Cohen's Kappa) and not Fuzzy Kappa. Thanks anyway, PauloFR ?s 16:47 de 23/11/2021, ?????? ??????? escreveu:
Well, I could be wrong, but I suspect, that you can try "goofcat" function from "ithir" package. Link to pkg -https://bitbucket.org/brendo1001/ithir/src/master/. Andrey 23.11.2021, 18:03, "Paulo Flores Ribeiro"

According to Hagen?Zanker (2009:
https://doi.org/10.1080/13658810802570317), ?The Fuzzy Kappa
statistic
expresses the agreement between two categorical raster maps. The
statistic goes beyond cell?by?cell comparison and gives partial
credit
to cells based on the categories found in the neighborhood.?
Does anyone know of a package/function to compute such a Fuzzy
Kappa
statistic in R?
Thanks in advance,
PauloFR
