Greg Bowyer updated SOLR3673:

Description:
Hi all
At my $DAYJOB I have been asked to build a few random variate functions that return random
numbers bound to a distribution.
I think these can be added to solr.
I have a hesitation in that the code as written uses / needs uncommons math (because we want
a far better RNG than java's and because I am lazy and did not want to write distributions)
uncommons math is apache license so we are good on that front
anyone have any thoughts on this ?
For reference the functions are:
rgaussian(mean, stddev) > Random value aligned to gaussian distribution
rpoisson(mean) > Random value aligned to poisson distribution
rbinomial(n, prob) > Random value aligned to binomial distribtion
rcontinous(min ,max) > random continuous value between min and max
rdiscrete(min, max) > Random discrete value between min and max
rexponential(rate) > Random value from the exponential distribution
