If there is a more appropriate group for this, perhaps a
stats newsgroup, please let me know.
An aquaintance has a requirement for a large quantity of
truly random values. I believe the application for which
they are required is a genetic mutation simulator.
The way he has gone about getting this random data is a method
used in several encryption programs, namely asking the user to
type keys, and recording the intervals between keystrokes with
a hi-res timer. In fact, I believe he threw together a TSR
which trapped keystroke intervals over the course of a day or
so, in order to get a sufficient quantity of data.
This is fine as a random bitstream, but for his application,
he needs a set of random _values_, in a defined range, with
the constraint that there must be at least one of each
possible value. I am completely useless at stats, so could
people suggest how this might be achieved?
Thanks in advance.
