similar to: R-beta: Re: [S] pbinom

This came up due to a question from Anders Hald: Bernoulli calculated an approximation to the smallest n so that P(0.58 <= x/n <= 0.62) >= 1000/1001 What is the exact value? Now try n <- 6350:6500 Pr <- function(n)pbinom(0.62*n,n,0.6) - pbinom(0.58*n,n,0.6) + dbinom(0.58*n,n,0.6) plot(n,Pr(n),type="b") abline(h=1000/1001) min(n[Pr(n)>1000/1001]) Next, try Pr

Hello all, I am trying to understand the different results I am getting from the following 3 commands: chisq.test(c(62,50), p = c(0.512,1-0.512), correct = F) # p-value = 0.3788 binom.test(x=62,n=112, p= 0.512) # p-value = 0.3961 2*(1-pbinom(62,112, .512)) # p-value = 0.329 Well, the binom.test was supposed to be "exact" and give the same results as the pbinom, while the chisq.test

Full_Name: Chanseok Park Version: R 2.2.1 OS: RedHat EL4 Submission from: (NULL) (130.127.112.89) pbinom(any negative value, size, prob) should be zero. But I got the following results. I mean, if a negative value is close to zero, then pbinom() calculate pbinom(0, size, prob). dbinom() also behaves similarly. > pbinom( -2.220446e-22, 3,.1) [1] 0.729 > pbinom( -2.220446e-8, 3,.1)

Full_Name: Uffe H?gsbro Thygesen Version: 2.2.0 OS: linux Submission from: (NULL) (130.226.135.250) Hello all. pbinom(q=0,size=0,prob=0.5) returns the value NaN. I had expected the result 1. In fact any value for q seems to give an NaN. Note that dbinom(x=0,size=0,prob=0.5) returns the value 1. Cheers, Uffe

I am using Ferret for a Rails app in which Rails runs as one user but I have other processes that run as a different user that modify the ferret index. This is done in large part to mitigate the damage if a major exploit is found in Rails again. The problem is Ferret creates all its index files with rw for the user only. I have included a small patch that changes Ferret to create these

The real problem is that pbeta can take forever. That's bug #7153 and a fix is within reach. Morten

Hi - I am not familiar with R. Could I ask you a quick question? When I read a file like this, I get an error. Not sure what I am doing wrong. I use a MAC. How do I specify a full path name for a file in R? Or do files have to reside locally? > KoreaAuto <- read.table(""/Users/ raviramaswamy/Documents/Rutgers/STT 586/HW1 Data.txt"") Error: unexpected numeric

Dear R users, I?m trying to optimize simultaneously two binomials inequalities (used in acceptance sampling) which are nonlinear solution, so there is no simple direct solution. Please, let me explain shortly the the problem and the question as following. The objective is to obtain the smallest value of 'n' (sample size) satisfying both inequalities: (1-alpha) <= pbinom(c, n, p1)

This is an inquiry for all those who have been working on external data base applications. I sent an inquiry (below) to snews about this sort of thing a couple of years ago and eventually decided that I would wait to see what external database developments occurred and then revisit the problem. I hope that foundations are now better. Suppose for the sake of concreteness you have a large

Hello all, A friend just showed me how ks.test fails to work with pbinom for small "size". Example: x<-rbinom(10000,10,0.5) x2<-rbinom(10000,10,0.5) ks.test(x,pbinom,10,0.5) ks.test(x,pbinom,size = 10, prob= 0.5) ks.test(x,x2) The tests gives significant p values, while the x did come from binom with size = 10 prob = 0.5. What test should I use instead ? Thanks, Tal

Dear R Users, Is the p-value reported in a two-tailed binomial exact test in error or is it a feature? If it is a feature, could someone provide a reference for its two-tailed p-value computations? Using Blaker's (2000 - Canad. J. Statist 28: 783-798) approach,the p-value is the minimum of the two-tailed probabilities $P \left(Y\geq y_{obs}\right)$ and $P\left(Y\leq y_{obs}\right)$

I'm trying to get some applications working on my Wine install, some applications just work without trouble (and even work better than on windows! A good example of this is Master of Orion III), however other applications don't work at all, and are supposed to be quite simple to get working (WoW, IE using any of three or four techniques I found online, etc). Are there anyapplications or

Dear R users, I?m trying to optimize simultaneously two binomials inequalities used to acceptance sampling, which are nonlinear solution, so there is no simple direct solution. The 'n' represents the sample size and the 'c' an acceptance number or maximum number of defects (nonconforming) in sample size. The objective is to obtain the smallest value of 'n' (sample size)
