Overview The loglogistic distribution is a probability distribution whose logarithm has a logistic distribution. This distribution is often used in survival analysis to model events that experience an initial rate increase, followed by a rate decrease. It is also known as the Fisk distribution in eco...
在生物学中,'log'可以用于描述生物种群的增长情况,如Logistic增长模型就是基于对数函数建立的。 此外,'log'在金融领域也有着重要的应用。例如,在金融投资中,对数收益率(log return)是一种常用的收益率计算方法,它可以更好地反映投资的长期增长情况。在风险管理领域,对数正态分布(log-n...

如果logistic是“物流的,后勤的”意思,那“logistics”是什么意思呢? logistic加上s,应该就不是形容词了。相比动词,logistics更可能是一个名词,难道是“物流,后勤”的意思? Bingo!猜对了! 总结一下: log→logist→logistic→logistics 记录、日志→逻辑学、逻辑学家→物流的、后勤的→物流、后勤 ...

The principle of maximum entropy (POME) was employed to derive a new method of parameter estimation for the 3-parameter log-logistic distribution (LLD3). Monte Carlo simulated data were used to evaluate this method and compare it with the methods of moments (MOM), probability weighted moments ...
illustrated that the Ex-LL distribution provided an adequate fit compared to other competing distributions such as the log-logistic, alpha-power log-logistic, transmuted log-logistic, generalized log-logistic, Marshall–Olkin log-logistic, inverse log-logistic, and Weibull generalized log-logistic ...
