sorry, you are right, I used exp(lnfactorial(x))... I have to calculate probabilities for observations to be sampled. That's why I use exp with lnfactorial...

Oops

di lnfactorial(180000) - (lnfactorial(2000)) + lnfactorial(180000-2000)

should be

di lnfactorial(180000) - (lnfactorial(2000) + lnfactorial(180000-2000))
