NO.PZ2015120604000056 问题如下 Whiof the following scriptions about leptokurtic is most appropriate? A.A stribution of returns thhextremely large viations from the meis positively skewe B.A stribution of returns thhextremely large viations from the mehpositive excess kurtosis. C.A stribution of returns thhextremely large viations from the mehnegative excess kurtosis. B is correctLeptokurtic refers to a stribution thha fatter tail tha normstribution(i.e.positive excess kurtosis). 为啥是偏离于均值

B is correctLeptokurtic refers to a stribution thha fatter tail tha normstribution(i.e.positive excess kurtosis). 这个是问L，尖峰肥尾；它的异常值是要比P（低峰瘦尾）要多的；B的答案是L跟自己比，因为excess K＞0的就是L，两个表达的是一个东西，不存在谁比谁的异常值多；C的答案是指题干的L，要比excesK＜0也就是P（低峰瘦尾）的异常值多，这样的是对的。所以不是应该选C吗
