Electrical rock typing using Gaussian mixture model to determine cementation factor

Journal of Petroleum Exploration and Production Technology, 2023
Many studies have worked on the estimation of fluid saturation as an important petrophysical property in hydrocarbon reservoirs. Based on Archie's law, proper determination of cementation factor (m) can lead to accurate values of water saturation.

Improve Akaike’s Information Criterion Estimation Based onDenoising of Quadrature Mirror Filter Bank

Al-Khawarizmi Engineering Journal, 2009
Akaike’s Information Criterion (AIC) is a popular method for estimation the number of sources impinging on an array of sensors, which is a problem of great interest in several applications. The performance of AIC degrades under low Signal-to-Noise Ratio (

Bootstrap Order Determination for ARMA Models: A Comparison between Different Model Selection Criteria

Journal of Probability and Statistics, 2017
The present paper deals with the order selection of models of the class for autoregressive moving average. A novel method—previously designed to enhance the selection capabilities of the Akaike Information Criterion and successfully tested—is now ...

A New Extended Rayleigh Distribution with Applications of COVID-19 Data

Austrian Journal of Statistics
In this manuscript, we proposed a new extension of the Rayleigh distribution named as MTI Rayleigh distribution (MTIRD) that provides better fits than the Rayleigh distribution and some of its known generalizations.

An information theory approach to hypothesis testing in criminological research

Crime Science, 2018
Background This research demonstrates how the Akaike information criterion (AIC) can be an alternative to null hypothesis significance testing in selecting best fitting models. It presents an example to illustrate how AIC can be used in this way. Methods
