Weibull-Fréchet distribution: A new lifetime distribution with application to gastric cancer data [PDF]

ITM Web of Conferences
Lifetime data is a type of data that consists of waiting time until an event occurs. Some of the events of lifetime data are deaths, occurrence of a disease, or failure of a machine. The distribution usually used for modeling lifetime data is the Weibull

Cumulative Residual q-Fisher Information and Jensen-Cumulative Residual χ² Divergence Measures

Entropy, 2022
In this work, we define cumulative residual q-Fisher (CRQF) information measures for the survival function (SF) of the underlying random variables as well as for the model parameter. We also propose q-hazard rate (QHR) function via q-logarithmic function

Maximum likelihood estimation of a log-concave density and its distribution function: Basic properties and uniform consistency [PDF]

, 2009
We study nonparametric maximum likelihood estimation of a log-concave probability density and its distribution and hazard function. Some general properties of these estimators are derived from two characterizations.

How can we learn what attention is? Response gating via multiple direct routes kept in check by inhibitory control processes

Open Psychology, 2020
To explore the time course of space- and object-based attentional selection processes I analysed the shapes of the response time (RT) and accuracy distributions of left/right arrow identification responses in the two-rectangle paradigm.
