Calculate Errors for leaf in a Decision Tree C4.5?
"For a confidence level CF, the upper limit on this probability can be found from the confidence limits for the binomial distribution. This upper limit here is written U_cf(E,N)"
where E is incorrectly classified events and N is total events in the leaf. He has a example with a confidence level of 25%, N=6 and E=0 and he calculates the error to U_25%(0,6) = 0.206. Could anyone explain how this is actually calculated? I have had no luck searching for it. Thank you for any help!
