Hi,
In S+/R, is there an easy way to generate random numbers with a
probability distribution specified by an exact user-defined function?
For example, I have a function:
f(x) = 1/(365 * x), which should be fitted for values of x between 1 and
100,000
How do I generate random numbers with a probability distribution that
exactly maps the above function?
You can use sample() with the prob argument set to the values of f(x).
You probably want replace=TRUE as well.
