Fisher Exact test on rxc tables

Post by siyisoy »

Hi
Fisher exact tests seems to be available only for 2x2 tables.
Can I perform it for bigger tables?

Nope, at least not in jamovi at the moment :slightly_smiling_face:

if you create an issue on our issues page, we'll see about broadening this:

I bump this up because I'm interested in being able to perform a Fisher"s exact test when comparing proportions (instead of a khi²).

Have a nice day.

Is it possible to do a Fisher Exact test on a bigger matrix than 2x2 using the Rj editor.

I tried fisher.test(data[c(1:2)]) but got the error message "all entries of 'x' must be nonnegative and finite. I get this whether the data in columns 1 and 2 form a 2x2 table or a 3x2 table. I get the same for fisher.test(data[c('A','B')])

The other version of the syntax I tried was fisher.test(data[c(1)],data[c(2)]) which produces 'x' must have at least 2 rows and columns.

Any ideas?

Cheers,

Wake

Am I right thinking that by now (current version of jamovi) it is possible to use the Fisher's exact test for contingency tables bigger than 2x2? :)
