Generalized Fiducial Inference for the Generalized Rayleigh Distribution

open access: yesModelling, 2023
This article focuses on the interval estimation of the generalized Rayleigh distribution with scale and shape parameters. The generalized fiducial method is used to construct the fiducial point estimators as well as the fiducial confidence intervals, and

Mapping the origins of time: Scalar errors in infant time estimation [PDF]

open access: yes, 2014
Time is central to any understanding of the world. In adults, estimation errors grow linearly with the length of the interval, much faster than would be expected of a clock-like mechanism.
