Although this method does not need to know the baseline hazard function, it cannot estimate event time ratio (ETR) which measures relative increase or decrease in survival time. To estimate ETR, the Weibull parametric model needs to be applied. The objective of this study is to develop and ...
其意义为,当解释变量X每升高一个单位,失效事件的发生风险率是原水平的exp(β)或100exp(β)%。 第二种思路是用解释变量对生存时间建模:加速失效时间模型(Accelerated Failure-time (AFT) model),其假设是解释变量的效应与生存时间是相乘关系(成比例的,Multiplicative effect with survival time)。因为生存时间存在截...

第二种思路是用解释变量对生存时间建模:加速失效时间模型(Accelerated Failure-time (AFT) model),其假设是解释变量的效应与生存时间是相乘关系(成比例的,Multiplicative effect with survival time)。因为生存时间存在截尾值,且为非负值,直接将生存时间作为因变量构建回归模型会受到很大限制,两侧值域也可能不一致。经自然...

WEIBULL is a FORTRAN program which calculates the regression coefficients, their standard errors and the maximised log-likelihood of the data for a Weibull regression model. It incorporates routines from the NAG library in order to perform the maximisation. A x2 statistic is computed to check the...

This paper aims to extend their model to the more flexible Weibull distribution. We derived theoretical correlations among different survival outcomes, as well as the distribution of overall survival induced by the model. Model parameters were estimated by the maximum likelihood method and the ...
