Hello all:
Is it possible to generate quasi-random positive numbers, given a standard
deviation and mean? I need all positive values to have the same probability
of selection (uniform distribution). Something like:
runif(10, min = 0, max = 100)
This way I'm generating random positive numbers from a uniform
distribution. However, using runif I can't previously select SD and mean
(as in rnorm).
Alternatively, I'm able to generate a list of quasi-random numbers given a
SD and a mean.
b <- (sqrt(SD^2*12)+(MEAN*2))/2
a <- (MEAN*2) - b
x1 <- runif(N,a,b)
However, negative values might be included, since "a" can assume a negative
value.
Any help?
Thanks,
Frederico
