WebMar 24, 2024 · 正态分布标准化需要除以标准偏差，标准偏差的量纲与变量一致，这样就可以消除量纲了。 让每一个变量x与变量x的均值的差，都除以x的标准偏差Sx，变量y也同理，则有以下关系式：（该关系式即为皮尔逊相关系数，简称相关系数，可以认为是协方差的标准 … The Pearson distribution is a family of continuous probability distributions. It was first published by Karl Pearson in 1895 and subsequently extended by him in 1901 and 1916 in a series of articles on biostatistics. See more The Pearson system was originally devised in an effort to model visibly skewed observations. It was well known at the time how to adjust a theoretical model to fit the first two cumulants or moments of observed data: Any See more Case 1, negative discriminant The Pearson type IV distribution If the discriminant of the quadratic function (2) is negative ($${\displaystyle b_{1}^{2}-4b_{2}b_{0}<0}$$), it has no real roots. Then define See more These models are used in financial markets, given their ability to be parametrized in a way that has intuitive meaning for market traders. A number of models are in current use that capture the stochastic nature of the volatility of rates, stocks, etc., and this … See more Primary sources • Pearson, Karl (1893).
