Thread: Chi square test

Hi All,

I have some data in my C code, I want to execute chi-square test on those data.

I can have observed, expected values as well as the chisquare value, but I have no clue how to calculate the chi square distribution value.

I can write a program in R to compute the "pvalue" of the chisquare test, but I am not being able to call that R function from C.

Do you have any idea about how can I use execv()(or similar) function to execute R functions ?

Thanks a bunch,

Let me google that for you

Hi tabstop,

I did not find anything while googling that.. Please do let me know if you get something!!

I wouldn't keep hunting for it if the hits on Google don't show what you need. It's been two days.

What do you think about writing that one function, in C? If you have a template for it (the function in R), it doesn't sound too difficult.

what is chi square test man ?

I know very little about it. If I understand it right, it's a statistics test which can tell you if the data you've received is within the expected range.
