Statistical Inference For The Modified Weibull Model Based On The Generalized Order Statistics, M. Maswadah, M. Seham May 2023

Statistical Inference For The Modified Weibull Model Based On The Generalized Order Statistics, M. Maswadah, M. Seham

Journal of Statistics Applications & Probability

In recent years, a new class of models has been proposed to exhibit bathtub-shaped failure rate functions. The modified Weibull is one of these models, which is a generalization for the Weibull distribution and is capable of modeling bathtub-shaped and increasing failure rate lifetime data. In this paper, conditional inference has been applied to constructing the confidence intervals for its parameters based on the generalized order statistics. For measuring the performance of this approach compared to the Asymptotic Maximum Likelihood estimates (AMLEs), simulations studies have been carried out for different values of sample sizes and shape parameters. The simulation results …

Efficient Circular Designs Partially Balanced For Residual Effects In Periods Of Three Different Sizes, Muhammad Ejaz Malik, Muhammad Shahbaz, Muhammad Daniyal, Khadim Hussain, Muhammad Riaz, Rashid Ahmed May 2023

Efficient Circular Designs Partially Balanced For Residual Effects In Periods Of Three Different Sizes, Muhammad Ejaz Malik, Muhammad Shahbaz, Muhammad Daniyal, Khadim Hussain, Muhammad Riaz, Rashid Ahmed

Journal of Statistics Applications & Probability

To estimate the treatment effects using repeated measurements designs (RMDs), residual effects often become the major source of bias. Minimal balanced RMDs are well known economical designs to minimize bias due to these effects for v odd, where v is the number of treatments to be compared. For v even, partially balanced RMDs are preferred. In this article, catalogues of two main classes of minimal circular partially balanced RMDs are compiled in periods of three different sizes. These designs possess high efficiency of residual effects and of Separability, therefore, our proposed designs are efficient.

Journal of Statistics Applications & Probability

The functional variational principle and differential equations of motion for the Lee–Wick electrodynamics equation are investigated in this study. A functional Hamiltonian principle is built utilizing the concept of a functional derivative. The Hamiltonian formulation of third-order continuous field systems is created using functional derivatives for continuous third-order systems. The formalism is generalized, and this new formulation is used to solve the Lee–Wick electrodynamics equation. We used the Euler-Lagrange equations for these systems to compare the results obtained using Hamiltons equations in terms of functional derivatives. To compare the outcomes of the two methodologies in terms of functional derivatives, one …

The Performance Of Quantile Regression And Linear Regression With Heteroskedasticity Was Compared In A Simulated Study, Marwa R. Saad, Ahmed H. Youssef, Shereen H. Abdel Latif May 2023

The Performance Of Quantile Regression And Linear Regression With Heteroskedasticity Was Compared In A Simulated Study, Marwa R. Saad, Ahmed H. Youssef, Shereen H. Abdel Latif

Journal of Statistics Applications & Probability

The least-square estimator has several drawbacks when dealing with heteroscedasticity; this estimate will not be a Best Linear Unbiased Estimator (BLUE). Quantile Regression is a dependable option; however, it has some substantial computational problems. We compare five resampling approaches to estimate the standard error of the coefficients, in the situation of heterogeneity, for inference. According to simulation study, quantile regression beats linear regression and is also better when predicting errors in the presence of heterogeneity.
