A note on the estimation of the Poisson parameter
International Journal of Mathematics and Mathematical Sciences, Volume 8, Issue 1, Page 193-196, 1985., 1985 This paper considers the problem of estimating the mean of a Poisson distribution when there are errors in observing the zeros and ones and obtains both the maximum likelihood and moments estimates of the Poisson mean and the error probabilities. It is interesting to note that either method fails to give unique estimates of these parameters unless the ...

Maximum Fisher information in mixed state quantum systems
, 2004 We deal with the maximization of classical Fisher information in a quantum system depending on an unknown parameter. This problem has been raised by physicists, who defined [Helstrom (1967) Phys. Lett.

A note on the maximum likelihood estimator in the gamma regression model [PDF]
, 2009 This paper considers a nonlinear regression model, in which the dependent variable has the gamma distribution. A model is considered in which the shape parameter of the random variable is the sum of continuous and algebraically independent functions. The

Varieties with maximum likelihood degree one
, 2014 We show that algebraic varieties with maximum likelihood degree one are exactly the images of reduced A-discriminantal varieties under monomial maps with finite fibers.

Measuring inequality: application of semi-parametric methods to real life data
, 2017 A number of methods have been introduced in order to measure the inequality in various situations such as income and expenditure. In order to curry out statistical inference, one often needs to estimate the available measures of inequality.

Statistical inference and data analysis of the record-based transmuted Burr X model
Open MathematicsProbability distribution has proven its usefulness in almost every discipline of human endeavors. A novel extension of Bur X distribution is developed in this study employing the record-based transmuted mapping technique, which can be used to fit skewed ...

Large deviations for i.i.d. replications of the total progeny of a Galton--Watson process
, 2017 The Galton--Watson process is the simplest example of a branching process. The relationship between the offspring distribution, and, when the extinction occurs almost surely, the distribution of the total progeny is well known.

Journal of Mathematics, Volume 2025, Issue 1, 2025.This article aims to present a new type‐II claims Pareto extension for statistical reliability and actuarial analysis. The new probabilistic density can be simplified in terms of the baseline densities. Some new bivariate types were developed under some copula approaches.

Journal of Mathematics, Volume 2025, Issue 1, 2025.This paper investigates the use of shrinkage estimators in the generalized Poisson hurdle (GPH) model for count data analysis. The GPH model effectively handles data with both excess zeros and over‐ or underdispersion. We propose shrinkage estimators to improve parameter estimation in this model and analyze their asymptotic properties, including biases

Estimation of Power Lomax Distribution for Censored Data With Applications
Journal of Mathematics, Volume 2025, Issue 1, 2025.In this study, power Lomax (PL) distribution parameters are estimated under an adaptive Type‐II progressive censoring scheme, utilizing both frequentist and Bayesian statistical estimations. The model parameters, reliability and hazard functions, and coefficient of variation are all determined using an iterative procedure in the frequentist estimation.
