Sum of binominal distributed random numbers
Hi
I have two vectors, prob and size, and I want to add the random deviates
of these two, i.e.
sum(
sapply(
1:length(prob),
function(n){ rbinom(1, size(n), prob(n) }
)
)
My problem is that I have to do this for a large number of value
combinations. Is there a faster way of doing this?

[help] simulation of a simple Marcov Stochastic process for population genetics
Hi, this is my first time using R. I want to simulate the following process:
"in a population of size N, there are i individuals bearing genotype A, the
number of those bearing A is j in the next generation, which following a
binominal distribution (choose j from 2*N, the p is i/2*N), to plot the
probability of the next generations, my script is as follows. It cannot run
successfully, declaring that the "ylim should be limited. " I wonder where
the bug is. Thanks very much!
generation<-function(i,N)

R commands
...Recently I conduct a project about expected return that
involves using R for calculations. I encounter three questions as follow:
Q1. How to use R to demonstrate bootstrapping and Monte Carlo simulation
under 10,000 times of random selection?
Q2. How to do a loop in R?
Q3. How to use R to do binominal tree calculation under multiple periods?
I'm perplexed by the R commands, so any hints or examples will be highly
appreciated.
Andy

outout clarification of fitdist {fitdistrplus} output
Hello,
I like to fit data against a negative binominal distribution
x2<-c(rep(10,14),rep(9,8),rep(8,13),rep(7,11),rep(6,6),rep(5,18),rep(4,7),re
p(3,21),rep(2,33),rep(1,55),rep(0,225))
f2<-fitdist(x2,"nbinom",method="mle")
plot(f2)
summary(f2)
gofstat(f2)
I receive the following result:

Multiple test of proportion in r
...4
1 BONO6EUROS 626 1793
What I want achive is if there is a redemption or purchasing rate significatively different between each group, and see between which group there is difference
Now, I have the following doubts:
a. I understand I should run a multiple comparison test, like maybe a GLM with binominal distribution, but I'm not sure it is a correct procedure, considering that some of the groups (for instance the fourth one, with n=83) are quite smaller than the main other groups. Is the model I choose the correct one for this kind of analysis, and I should exclude the smaller groups?
b. I un...

Problem with mle
R 2.3.0
Linux, SuSE 10.0
Hi
I have two problems with mle - probably I am using it the wrong way so
please let me know.
I want to fit different distributions to an observed count of seeds and
in the next step use AIC or BIC to identify the best distribution.
But when I run the script below (which is part of my original script), I
get one error message for the first call of mle:
Error in
