Thanks Martin. What if the dice were non-transitive? Is that where -simulate- comes into play in order to generate the roll outcomes? Say something like: Dice 1: 1, 4, 4, 4, 4, 4 so 4 is 5/6 and 1 is 1/6 RickOn Fri, Feb 20, 2009 at 3:17 PM, Martin Weiss <martin.weiss1@gmx.de>wrote:<>Normally, one would use -simulate- but this is more easily accomplishedas********* clear* set obs 10000 g firstdice=1+int(6*runiform()) g seconddice=1+int(6*runiform()) g sumofdice=firstdice+seconddice *let`s see whether CIs conform to our idea of unbiased dice prop sum ********** where you can edit the obs to the # of replications you want...

So there are 36 combinations of dice rolls and the sum will always be between 2 (1 and 1) and 12 (6 and 6). With a large number of simulations, we should get the probabilities of: 2: 1/36 = 0.02778 3: 2/36 = 0.05556 4: 3/36 = 0.08333 5: 4/36 = 0.11111 6: 5/36 = 0.13889 7: 6/36 = 0.16667 8: 5/36 = 0.13889 9: 4/36 = 0.11111 10: 3/36 = 0.08333 11: 2/36 = 0.05556 12: 1/36 = 0.02778 * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/* * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/* * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
