The probability of x, y and z is respectively is 0.3, 0.5, 0.2. I wan to simulate a new same size population based ratio of x, y and z, how can I get and assess the number of x, y and z. ? luan Key Laboratory for Sustainable Utilization of Marine Fisheries Resources, Ministry of Agriculture ,Yellow Sea Fisheries Research Institute, Chinese Academy of Fishery Sciences, Qingdao 266071,China __________________________________________________ ÂÑÂÅ»¢ÂÃÂâ·ÂÑGÂÓÂÊÂÃÂä£ÂÂÂÖÂùÂúµÂÚÂÒ»¾ÂøÂÃŽÂÞÂÀ¬»ÂøÂÓÂʼÂþÂɧÂÈÂų¬´ÂóÂÓÂÊÂÃÂä ______________________________________________ R-help at stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
