exponential family distribution(指数族分布) 1. exponential family 给定参数 η,关于 x 的指数族分布定义为如下的形式: p(x∣∣η)=h(x)g(η)exp{ηTu(x)} 其中x 可以为标量也可以为矢量,可以为离散也可是连续。其中 η 被称为分布的自然系数(natural parameters), g(η)∫h(x)exp{ηTu(x)}dx=1...
Returns the mean of an exponential distribution. double out = stdlib_base_dists_exponential_mean( 9.0 ); // returns ~0.111 The function accepts the following arguments: lambda: [in] double rate parameter. double stdlib_base_dists_exponential_mean( const double lambda ); Examples #include "std...
The paper investigates novel semiparametric estimators for survival distribution functions under an informative model with double censoring. We exploit the model's characterization properties to gain insights into the asymptotic behavior and efficiency of the proposed estimators. Additionally, we employ ...

Thus, the distribution function of the waiting times between events in a Poisson process is1−e−λt1−e−λt. With this, and recalling that our time-unittt is one minute and our rateλλ is two requests per minute, we can answer questions such as: ...

of the fields of a parametrization object stores a parameter over a specified support. Some parameters are marked as “fixed”, which means that they are fixed with respect to the exponential family. An example of a fixed parameter is the failure number of the negative binomial distribution. ...
