内容简介· ··· Get the first book to pull the vast literature on the Weibull into a proper perspective under one cover. "Weibull Models": covers model analysis, parameter estimation, model validation, and application; classifies the different models and their properties; intertwines theory ...
第一种思路是用解释变量对生存风险h(t)建模:比例风险模型(Proportional Hazards (PH) model),其假设是解释变量的效应与风险是相乘关系(成比例关系,Multiplicative effect with hazard)。 h0(t)被称为基线风险函数,定义为所有的解释变量X取值为0时的风险,所以基线风险函数实际上应该等于h0(t) exp(β0),也就是经...
Summary Type III models involve more than one distribution with one or more of them being the Weibull or the inverse Weibull model. These models can be categorised into four groups (Type III(a) to (d)). Type III(a) models are referred to as mixture models and are discussed in this ...

Finally, it showed that Weibull model has a larger AUC value than CPH model in general, and it also has smaller Brier score value for EC survival prediction using both training and testing datasets, suggesting that it is more accurate to use the Weibull model for EC survival analysis. ...
To forecast blasting muck pile form of high bench cast blasting,Weibull model was introduced as mathematical model to simulate actual muck pile curve,and then,used eight parameters that tested and proven to have influence on muck pile form and simulated Weibull control parameters,and bulk factor as...
