st: product function |

I would like to plot the probability that two people share a birthday as a function of the number of people in the room n. The formula is 1-product((366-i)/365,i,1,n) In TeX, it would be 1-\dprod\limits_{i=1}^{n}\frac{366-i}{365}. If I have a variable n={1,...,50}, how can I define the product within Stata? There does not seem to be math function that can do this. DVM _______________________________________________________________________________ Dimitriy V.
