The log-logistic model is a statistical regression model for a nonnegative random outcome variable. It is applicable in cases where the logarithmized outcome variable follows a logistic distribution. In survival analysis, it is used to model hazard rates that are initially increasing and finally dec...

The log-logistic model has flexible monotonic or nonmonotonic partial derivatives and thus is suitable to model various uni-type impairments. The proposed ALM metric adds the distortions due to each type of impairment in a log-logistic transformed space of subjective opinions. The features can be ...

After defining a new log-logistic model and studying its properties, some new bivariate type versions using “Farlie-Gumbel-Morgenstern Copula”, “modified Farlie-Gumbel-Morgenstern Copula”, “Clayton Copula”, and “Renyi’s entropy Copula” are derived. Then, using the Bagdonavicius-Nikulin ...
logestic regression model怎么写 logistic regression analysis,LogisticRegressionLogisticRegression即逻辑回归,又称作Logistic回归分析,是要预测的变量为有限个离散量(比如2个值)的回归分析问题,可以理解为对样本进行分类的学习方法。与LinearRegression相似,我
Con- trary to traditional methods assuming Gaussian-distributed observation errors, we supervise our inference framework under an (empirically validated) adaptive log-logistic dis- tribution model. Moreover, the log-logistic residual model generalizes well to different s...
