Performance of criteria for selecting evolutionary models in phylogenetics: a comprehensive study based on simulated datasets [PDF]

open access: yesBMC Evolutionary Biology, 2010
Background Explicit evolutionary models are required in maximum-likelihood and Bayesian inference, the two methods that are overwhelmingly used in phylogenetic studies of DNA sequence data.

Finite Sample Improvement of Akaike’s Information Criterion [PDF]

open access: yesIEEE Transactions on Information Theory, 2021
We emphasize that it is possible to improve the principle of unbiased risk estimation for model selection by addressing excess risk deviations in the design of penalization procedures. Indeed, we propose a modification of Akaike's Information Criterion that avoids overfitting, even when the sample size is small.

Parametric Models in Survival Analysis for Lung Cancer Patients

open access: yesIbn Al-Haitham Journal for Pure and Applied Sciences, 2021
The aim of this study is to estimate the survival function for the data of lung cancer patients, using parametric methods (Weibull, Gumbel, exponential and log-logistic).

Model selection in multivariate adaptive regressions splines (MARS) using alternative information criteria

open access: yesHeliyon, 2023
Multivariate Adaptive Regression Splines (MARS) is a useful non-parametric regression analysis method that can be used for model selection in high-dimensional data. Since MARS can identify and model complex, non-linear relationships between the dependent

Evaluation of the best fit distribution for partial duration series of daily rainfall in Madinah, western Saudi Arabia [PDF]

open access: yesProceedings of the International Association of Hydrological Sciences, 2014
Rainfall frequency analysis is an essential tool for the design of water related infrastructure. It can be used to predict future flood magnitudes for a given magnitude and frequency of extreme rainfall events.

Noise Suppression of Microseismic Signals via Adaptive Variational Mode Decomposition and Akaike Information Criterion

open access: yesApplied Sciences, 2020
Microseismic (MS) signals recorded by sensors are often mixed with various noise, which produce some interference to the further analysis of the collected data.

Information criteria for astrophysical model selection [PDF]

open access: yes, 2007
Model selection is the problem of distinguishing competing models, perhaps featuring different numbers of parameters. The statistics literature contains two distinct sets of tools, those based on information theory such as the Akaike Information ...
