Detecting Clinical Risk Shift Through log–logistic Hazard Change-Point Model

Mathematics
The change–point problem is about identifying when a pattern or trend shifts in time–ordered data. In survival analysis, change–point detection focuses on identifying alterations in the distribution of time–to–event data, which may be subject to ...

The Arcsine Log-Logistic Distribution and Its Applications

European Journal of Mathematics and Statistics
This article introduces Arcsine Log-logistic (AL-L) distribution which is a member of Arcsine-G family proposed by Rahman. The different properties of AL-L distribution have been discussed. The distribution of various order statistics are obtained. Maximum Likelihood Estimation (MLE) technique is used to estimate the model parameters.
