Dear Ravi,
It's already been suggested that you could disable warnings, but that's
risky in case there's a warning that you didn't anticipate. Here's a
different approach:
> kk <- k[k >= -1 & k <= n]
> ans <- numeric(length(k))
> ans[k > n] <- 1
> ans[k >= -1 & k <= n] <- pbeta(p, kk + 1, n - kk, lower.tail=FALSE)
> ans
[1] 0.000000000 0.006821826 0.254991551 1.000000000
BTW, I don't think that you mentioned that p = 0.3, but that seems
apparent from the output you showed.
I hope this helps,
John

Hi,
I would like to execute the following vectorized calculation:
ans <- ifelse (k >= -1 & k <= n, pbeta(p, k+1, n-k, lower.tail = FALSE), ifelse
(k < -1, 0, 1) )
For example:
k <- c(-1.2,-0.5, 1.5, 10.4)
n <- 10
ans <- ifelse (k >= -1 & k <= n, pbeta(p,k+1,n-k,lower.tail=FALSE), ifelse (k <
-1, 0, 1) )
Warning message:
In pbeta(p, k + 1, n - k, lower.tail = FALSE) : NaNs produced
print(ans)
[1] 0.000000000 0.006821826 0.254991551 1.000000000
The answer is correct. However, I would like to eliminate the annoying
warnings. Is there a better way to do this?
Thank you,
Ravi
