## SF comments

- (1) General. If I understand this function correctly, then it is calculating the area under the chi-square probability density function curve to the right of the specified chi-square value. If this is correct, would it be worth stating?
- (2) General. We need to be consistent how we write “chi-square”. At the moment this page has spellings with both lower case and upper case “C”; also with and without a hyphen; also with both “square” and “squared”.
- (3) Summary. Would it be worth having “(observed value-expected value)^2/expected value” as a Math equation rather than inline text?
- (4) Summary. Should the words “right-tailed” appear somewhere in this summary?
- (5) Arguments, 1st bullet point. Should “or” appear before “equal”? Also spurious space before final full stop.
- (6) Arguments. 3rd bullet point. Change “in an” to “to an”.
- (7) Arguments. Case where
**DegreesFreedom**is not a number at all not covered. - (8) Arguments. I am confused by the equation and the Wikipedia link - both refer to the chi distribution rather than the chi-square distribution.
- (9) Examples. Please remove spelling errors from the second example – “Chis” and “randome”. Also change second occurrence of “value” to “values”.
