 gamma distribution
 A new estimate of shape parameter in the family of Gamma distribution In this paper, a new estimator of the shape parameter in the family of Gamma distribution is constructed by using the moment idea, and it is proved that this estimator is strongly consistent and asymptotically normal. Application of the theory of truncated probability distributions to studying minimal river runoff: Normal and gamma distribution Content subscribing mechanism in P2P streaming based on gamma distribution prediction From statistical regress, it was also found that the DSD follows the Gamma distribution best in most cases. 更多
 the gamma distribution
 From statistical regress, it was also found that the DSD follows the Gamma distribution best in most cases. Various cases of distributions, the δ-function, the exponential, and the Gamma distribution, are discussed. Maximum likelihood estimators have been developed for the gamma distribution when there is missing time-to-failure information. Maximum likelihood estimators are derived and demonstrated for the gamma distribution based on merged data records where the individual failure times have not been recorded. These results are important because the gamma distribution can model diverse time-to-failure behavior. 更多

 At present, the problem of determining the distribution function of Gamma distributed random variables's function, has not yet been well solved. But in the field of hydrologichydraulic calculation, we often have to deal with it. In this paper, on the basis of the basic probability theory, the joint distribution function of the sum and difference of two random variables, independent of each other and Gamma distributed, is developed in the form expressed by primary functions. 目前,对于GAMMA分布随机变数的函数的分布函数研究得不甚深入。但在水文水利计算等领域,却常要涉及这个问题。本文基于概率原理,导出用初等函数形式表达的相互独立两GAMMA分布随机变数之和与差的联合分布函数。 The author has constructed the squared error loss empirical Bayes estimations of location parameter about a class of gamma distributions and establi. shed their rates of convergence.
