st: censored random normal with a fixed mean and standard deviation |

In generating censored random normal variate with a fixed mean and standard deviation is there a way to determine what the mean and standard deviation should be for the uncensored normal. For exmaple, if one wants a cenored normal (at 0) with mean 25 and standard deviation 30, then -gen yield = max(0, rnormal(25,30))- will result in a mean too large and standard deviation too small. In this example values of -rnormal(13.5,43.75)- work, but is there way to determine what the uncensored mean and standard deviation should be? clear set obs 1000000 set seed 123456 gen yield1 = max(0, rnormal(25,30)) gen yield2 = max(0, rnormal(13.5,43.75)) sum Scott * * 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/
