I notice you reference some variables in your function: N, n, q, p_0, k, L, f_1, f_2. Could you define those (and any others) for us? After struggling with this myself, I got into the habit of starting a new R session and testing the code I was going to email, before hand. It helps to notice missing variables, libraries that need to be loaded, etc. > for(i in 1:N) { > X_0=rmultinom(q-1,size=1,prob=p_0) > X_1=rmultinom(n-q+1,size=1,prob=cbind(p_11,p_12,(1-p_11-p_12))) One other minor point, if you assign: cbind(p_11, p_12, (1 - p_11 - p_12)) to a variable (*outside* the for loop), it should speed things up a bit (you use it 3 times every single loop, I think) > N_0=apply(X_0[,(n-2*k-L+1):(n-k-L)],1,sum) > N_1=apply(X_1[,(n-q-k+2):(n-q+1)],1,sum) > S_vek[i]=((sum(((N_1-k*cbind(p_11,p_12,(1-p_11-p_12)))^2)/k*cbind(p_11,p_12,(1-p_11-p_12))))/(sum(((N_0-k*p_0)^2)/k*p_0)))-1 > } > 1-mean(f_1<=S_vek & S_vek <=f_2) > } > > An other problem i have is when i define > > p_11=seq(0,1,0.1) > p_12=seq(0,1,0.1) > then i get also this error message: > Error in rmultinom(n - q + 1, size = 1, prob = rbind(p_11, p_12, (1 - : > non-positive probability > > i cannot solve this problem too. > > Thank you for your time and sorry for my english. I am from germany.
