 Author Comment/Response Cheongsun 04/25/01 4:34pm I am writing to ask how can I get a step-by-step procedure to get a partial derivative of the following binomial function.I cannot remember exactly but, What I did was, (Clear[a, p, r, n] (k[p_] := (ap^r) ((1 - p))^(n - r); (j[p_] := Log[k[p]]; [PartialD]_p j[p]) I want to get a partial derivative by p, that is Dp K[p] I know the answer is (r/p) + (r-n)/(1-p) However, What I got was something else. !((-((n - r)/(1 - p)))) That is, - (n-r)/(1-p). I hope to get a step-by-step procedure to get partial derivative on that function. Thank you very much for your help. In addition, I hope I could plot a ''standardized normal distribution'' and get Mean (first moment), variance (second moment), Kurtosis(third moment) and so forth. I hope I could get the visualization of the process of getting moments out of normal distribution. Thank you again for your help. Regards, pcsjes URL: ,
