Ranuni from a uniform distribution on the interval from 0 to 1 and rannor from a normal distribution with a mean of 0 and standard deviation of 1.</P><P></P><P>Uses are many depending on your needs but basically revolve around a need for a random number. One example would be to add a value to set of data and use a specified subset of the data to select a random sample. For instance add a value x=ranuni (12345); to each record of a data set and then select x &lt; .20 to get roughly a 20 percent random sample of the data.</P></BODY></HTML> Mon, 27 Apr 2015 14:41:24 GMT https://communities.sas.com/t5/SAS-Procedures/Ranuni-Rannor-functions/m-p/204551#M50977 ballardw 2015-04-27T14:41:24Z
