单峰分布偏度计算公式改进的研究

Unimodal distribution, including symmetrical and asymmetrical distribution skewed distribution, the need for oblique degree with variation indicators to determine whether the unimodal distribution of the degree of symmetry and skew. Oblique degree as a result of the traditional formula for calculating the objective existence of the problem of insufficient to determine the error caused. \" Unimodal distribution oblique degree decision method inquisition\" to the existing formula for calculating the oblique degree an initial improvement, but not perfect. In this paper on the basis of further ameliorate. The purpose is: an objective reflection of the skewed unimodal distribution of the extent.
