Unit Exponential Probability Distribution: Characterization and Applications in Environmental and Engineering Data Modeling

open access: yesMathematics, 2023
Distributions with bounded support show considerable sparsity over those with unbounded support, despite the fact that there are a number of real-world contexts where observations take values from a bounded range (proportions, percentages, and fractions ...

Nonparametric estimation of a convex bathtub-shaped hazard function

open access: yes, 2010
In this paper, we study the nonparametric maximum likelihood estimator (MLE) of a convex hazard function. We show that the MLE is consistent and converges at a local rate of $n^{2/5}$ at points $x_0$ where the true hazard function is positive and ...

Nonparametric analysis of the time structure of seismicity in a geographic region

open access: yesAnnals of Geophysics, 2002
As an alternative to traditional parametric approaches, we suggest nonparametric methods for analyzing temporal data on earthquake occurrences. In particular, the kernel method for estimating the hazard function and the intensity function are presented ...
