| Abstract: | Based on the item and class response table worked out for 17 feat-ures of 23 Yanling subus.praecox(Conolor groups)specimens,the fuzzy sim-ilarity coefficient is defined and its matrix is Calculated.And then the Yan-ling subus.praecox is divided into 13 classes by means of maximum tree met-hod.This provides a quantitive evidence for further naming the Yanling sub-us.praecox.In the study,introducing a matching coefficient into the definat-ion of fuzzy similarity coefficient not only gives a solution to the differentweight combined morking problem but also offers an efficient mathmatic meth-od for classifying the population that have many non-quantitive features. |
