How Robust is Robust Control in the Time Domain? [PDF]

open access: yes
By applying robust control the decision maker wants to make good decisions when his model is only a good approximation of the true one. Such decisions are said to be robust to model misspecification.

Agent‐based versus correlative models of species distributions: Evaluation of predictive performance with real and simulated data

open access: yesMethods in Ecology and Evolution
Species distribution models (SDMs) have been widely used in ecology to understand how species relate to environmental variation. Most SDMs are correlative, and they lack explicit reference to the underlying processes, and therefore, the reliability of ...

Panel AR(1) estimators under misspecification

open access: yes
This short note derives the probability limits of several estimators for panel AR(1) models under misspecification using sequential asymptotics. The results show that GMM estimators based on the forward orthogonal deviation transformation converge to the

Revisiting Simpson's Paradox: a statistical misspecification perspective

open access: yes, 2016
The primary objective of this paper is to revisit Simpson's paradox using a statistical misspecification perspective. It is argued that the reversal of statistical associations is sometimes spurious, stemming from invalid probabilistic assumptions ...

Robust Design and Misspecification Detection for Count Models

open access: yes
Count models, such as the Poisson and negative binomial models, are widely utilized in various fields, including epidemiology, engineering, and social sciences, to model the occurrence of events within fixed periods of time or space.

Exchange Rate Expectations and Functional Misspecification.

open access: yes
The authors employ the Cooley-Prescott adaptive model to examine for functional misspecification in three commonly used exchange rate expectation models. They also test for heterogeneity among forecasts.

Robustness to model misspecification in Bayesian experimental design

open access: yes
Scientific experiments can be costly to conduct due to various reasons. Therefore, researchers need to choose the experimental design which allows them to obtain the highest amount of information possible. As an information-theoretical framework based on

Model Misspecification and Underdiversification

open access: yesThe Journal of Finance, 2001
AbstractIn this paper, we study intertemporal portfolio choice when an investor accounts explicitly for model misspecification. We develop a framework that allows for ambiguity about not just the joint distribution of returns for all stocks in the portfolio, but also for different levels of ambiguity for the marginal distribution of returns for any ...

The Misspecification of Arma Models

Statistica Neerlandica, 1989
The object of this paper is to assess the effects of fitting a model of the wrong order to a time series which is generated by an autoregressive moving–average process. The method is to examine the spectral density functions which are indicated by the probability limits of the least–squares estimators of the misspecified models.

The Effects of Misspecification of a Regression Model

Biometrical Journal, 1987
AbstractThe consequences of the misspecification of a regression model are considered. For small effects of covariates a proportional consistency theorem is derived. The consistent estimation of the covariance matrix of the estimates is discussed.
