Model Selection in Threshold Models [PDF]

Journal of Time Series Analysis, 2001
This paper considers information criteria as model evaluation tools for nonlinear threshold models. Results concerning the consistency of information criteria in selecting the lag order of linear autoregressive models are extended to nonlinear autoregressive threshold models.

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

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 ...

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.

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

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.

Bayesian outcome selection modeling

Stat, 2023
In psychiatric and social epidemiology studies, it is common to measure multiple different outcomes using a comprehensive battery of tests thought to be related to an underlying construct of interest. In the research that motivates our work, researchers wanted to assess the impact of in utero alcohol exposure on child cognition and neuropsychological ...

Evaluating Automatic Model Selection [PDF]

Journal of Time Series Econometrics, 2011
We outline a range of criteria for evaluating model selection approaches that have been used in the literature. Focusing on three key criteria, we evaluate automatically selecting the relevant variables in an econometric model from a large candidate set.

Selective scene modeling

[1992] Proceedings. 11th IAPR International Conference on Pattern Recognition, 2003
Proposes an efficient architecture for selective image modeling. The authors give an example in which models of different scale are reconstructed in parallel. It is shown that this redundant representation can effectively be pruned using the criterion of minimum description length.

Model selection for amplitude analysis [PDF]

, 2015
Model complexity in amplitude analyses is often a priori under-constrained since the underlying theory permits a large number of possible amplitudes to contribute to most physical processes.
