I welcome someone checking to see if my mathematics is correct! Right now, the information on this test on the web is really rather confusing, being mostly written by and for people who assume you have been taught it all manually in undergraduate statistics or are reading off from a printed table. —Donal Fellows 12:13, 9 August 2009 (UTC)
- My own statistics are rusty, and I am not familiar enough with the TCL math::statistics library to know how to check your math. That said, I think I would be helped if you specified which Chi-square test you have implemented (Pearson's?). Rdm 18:37, 8 September 2009 (UTC)
