Long-tailed distributions of inter-event times as mixtures of exponential distributions [PDF]

open access: yesRoyal Society Open Science, 2020
Inter-event times of various human behaviour are apparently non-Poissonian and obey long-tailed distributions as opposed to exponential distributions, which correspond to Poisson processes.

Understanding Recovery Is as Important as Understanding Decline: The Case of the Crested Ibis in China

open access: yesLand, 2022
The wild population of the crested ibis (Nipponia nippon) has recovered remarkably from seven individuals in 1981 to over 7000 in 2021. However, it is unclear how key factors, from endogenous density dependence to exogenous environmental pressure, have ...

Forecasting Industrial Production Using Its Aggregated and Disaggregated Series or a Combination of Both: Evidence from One Emerging Market Economy

open access: yesEconometrics, 2022
In this paper, we address whether using a disaggregated series or combining an aggregated and disaggregated series improves the forecasting of the aggregated series compared to using the aggregated series alone.

Selecting a Model for Forecasting [PDF]

open access: yesEconometrics, 2021
We investigate forecasting in models that condition on variables for which future values are unknown. We consider the role of the significance level because it guides the binary decisions whether to include or exclude variables. The analysis is extended by allowing for a structural break, either in the first forecast period or just before.

On model selection in cosmology [PDF]

open access: yesSciPost Physics Lecture Notes, 2019
We review some of the common methods for model selection: the goodness of fit, the likelihood ratio test, Bayesian model selection using Bayes factors, and the classical as well as the Bayesian information theoretic approaches. We illustrate these different approaches by comparing models for the expansion history of the Universe.

Comparing Genomic Prediction Models by Means of Cross Validation

open access: yesFrontiers in Plant Science, 2021
In the two decades of continuous development of genomic selection, a great variety of models have been proposed to make predictions from the information available in dense marker panels.

A conceptual framework for the dynamic modeling of time-resolved phenotypes for sets of genotype-environment-management combinations: a model library

open access: yesFrontiers in Plant Science, 2023
IntroductionDynamic crop growth models are an important tool to predict complex traits, like crop yield, for modern and future genotypes in their current and evolving environments, as those occurring under climate change. Phenotypic traits are the result

Comparing Model Selection Criteria to Distinguish Truncated Operational Risk Models

open access: yesFrontiers in Applied Mathematics and Statistics, 2020
In this paper three information criteria are employed to assess the truncated operational risk models. The performances of the three information criteria on distinguishing the models are compared.

Trends in Growth Modeling in Fisheries Science

open access: yesFishes, 2021
Growth models estimate life history parameters (e.g., growth rates and asymptotic size) that are used in the management of fisheries stocks. Traditionally in fisheries science, it was common to fit one growth model—the von Bertalanffy growth model—to ...

Model Fit and Model Selection [PDF]

open access: yesReview, 2007
This paper uses an example to show that a model that fits the available data perfectly may pro vide worse answers to policy questions than an alternative, imperfectly fitting model. The author argues that, in the context of Bayesian estimation, this result can be interpreted as being due to the use of an inappropriate prior over the parameters of shock
