 Oct25 comment How to correctly apply the Nemenyi post-hoc test after the Friedman test Dividing by (k-1) is when you compare multiple algorithms against a control method. But this a each versus each, so NxN. The dividing part I can understand, but the relation to the Studentized range distribution is beyond my understanding. Oct21 comment Hoops in a Field I think that is not enough information. When you say, a proportion of a field is covered in water, is there any additional knowledge about the form of that proportion? Is it one connected area? Are there constraints to the form? For example, imagine an area stretched zig zag over the whole area, but only covering 10%. For a certain, not small size of the hoop, the probability of water inside it will be 1.

(I have an R script for this, I'm searching for it right now) Sep29 awarded Teacher Jun14 awarded Scholar Jun14 accepted How do I get a $p$-value from the Cochran-Armitage trend test? Jun14 comment How do I get a $p$-value from the Cochran-Armitage trend test? Nevermind, I just got it. For $df = 1$, the Chi-squared distribution is the same as a single squared normal distributed variable, hence the equality. I really should read up more on statistics ;) Jun14 awarded Editor Jun14 revised How do I get a $p$-value from the Cochran-Armitage trend test? Put finaly question at the end and clarified question as in the title Jun14 comment How do I get a $p$-value from the Cochran-Armitage trend test? Thanks, but I've seen this two links before and neither one tells my how to get the p-value afterwards. Jun14 comment How do I get a $p$-value from the Cochran-Armitage trend test? Sounds reasonably. But why does Wikipedia use the Normal distribution instead of the chi-squared one? Jun14 awarded Student Jun14 asked How do I get a $p$-value from the Cochran-Armitage trend test?
