Survival analysis is a fundame.tal tool in me.ical scie.ce.for time.to-e.e.t data. Howe.e., its application to colony organisms like.be.s pose. challe.ge. due.to the.r social nature. Traditional survival mode.s may not accurate.y capture.the.inte.de.e.de.ce.among individuals within a colony. Frailty mode.s, accounting for share. risks within groups, offe. a promising alte.native. This study e.aluate. the.pe.formance.of se.i-parame.ric share. frailty mode.s (gamma, inve.se.normal, and positive.stable.in comparison to the.traditional Cox mode. using be.s’ survival data). We.e.amine. the.e.fe.t of misspe.ification of the.frailty distribution on re.re.sion and he.e.oge.e.ty parame.e.s using simulation and conclude. that the.he.e.oge.e.ty parame.e. was more.se.sitive.to misspe.ification of the.frailty distribution and choice.of initial parame.e.s (cluste. size.and true.he.e.oge.e.ty parame.e.) compare. to the.re.re.sion parame.e..

为实现机场雷暴的精准检测,设计一种基于大气电场的机场雷暴监测预警方法。通过大气电场仪采集电场大数据,并实施缺失数据填补、干扰数据去噪处理。利用经验模态分解法分解大气电场数据,实现大气电场数据的频率分布和幅值分布特征提取。基于多元回归模型构建预测模型,以特征为输入,预测未来一段时间内的雷暴强度值。参考雷暴强度等级划分表,实现不同程度的机场雷暴监测预警。结果表明:雷暴强度预测结果与实际结果之间的可决系数均在0.9以上,比较接近1,说明雷暴强度预测结果与实际情况较为接近,证明所研究方法的监测预警效果较好。
