[R] calculate probability of union of independent events

Dear all, I am looking for a way to calculate the probability of the union of k independent events in R. Is there a function that takes a k-dimensional probability vector as input and returns p(A_1 U A_2 U...U A_k)? Thanks, Florian ___ Dr. Flor

[R] calculate probability circles

Hi, All, I want to have the 1%, 2%, 3%, ... contours for Dirichlet distribution. I need the exact contour circles (mathematically) instead of contour plots. Can anyone help me with this? Many thanks, Cindy [[alternative HTML version deleted]] ___

[R] calculate probability

Dear All I have some problem with calculate probability. Assume I have data with normal distribution with mean = 5 sd = 2. I want to approximate probability = 2.4. I used pnorm(2.4, 5, 2) - pnorm(2.4, 5, 2, lower.tail = FLASE), correct or not. Many Thanks Jumlong __

Re: [R] calculate probability

Dear Jumlong, Perhaps look at ?pnorm I am not really certain what you want to do. Are 2.4 and 2.9 scores or means? Is the variance 2? What distribution are you assuming these values come from? If you explain a bit more what you are after, we can help more. Cheers, Josh On Fri, Nov 5, 2010

[R] calculate probability

Dear All I have 2 value assume 2.4 and 2.9 and mean = 2 variance = with n = 10 I want to find probability = 2.4 and 2.9. How I can do this. Many Thanks. Jumlong -- Jumlong Vongprasert Assist, Prof. Institute of Research and Development Ubon Ratchathani Rajabhat University Ubon Ratchathani THAILAN
