isn't it binSize = 2 * IQR / N^(1/3) ?? —Preceding unsigned comment added by LN29 (talkcontribs)

wrong formula

edit

The formula as stated doesn't give anything remotely correct. Looking around on the web a formula that looks right and actually seems to work in my tests is:

(N^1/3 * range)/(2 * IQR)

Where range is the range of the data. —Preceding unsigned comment added by 64.157.93.210 (talkcontribs)


The formula listed is the formula found in the paper. Could you maybe be thinking of the number of bins rather than the bin size? (Lucas(CA) (talk) 19:07, 5 October 2016 (UTC))Reply
