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

Land, 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 ...

Econometrics, 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]
Econometrics, 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]
SciPost 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
Frontiers 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.

Frontiers 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

Trends in Growth Modeling in Fisheries Science
Fishes, 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 ...

Comparing Model Selection Criteria to Distinguish Truncated Operational Risk Models
Frontiers 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.

On Zero-Inflated Alternative Hyper-Poisson Distribution
Statistica, 2022 Here we develop a zero-inflated version of the alternative hyper-Poisson distribution and discuss its important statistical properties such as probability generating function, expressions for mean, variance, factorial moments, skewness, kurtosis ...
