Acknowledgement Misspecification in Macroeconomic Theory [PDF]

open access: yes
We explore methods for confronting model misspecification in macroeconomics. We construct dynamic equilibria in which private agents and policy makers recognize that models are approximations.

Applying the M2 Statistic to Evaluate the Fit of Diagnostic Classification Models in the Presence of Attribute Hierarchies

open access: yesFrontiers in Psychology, 2018
The performance of the limited-information statistic M2 for diagnostic classification models (DCMs) is under-investigated in the current literature. Specifically, the investigations of M2 for specific DCMs rather than general modeling frameworks are ...

Efficient Imitation under Misspecification

open access: yesCoRR
We consider the problem of imitation learning under misspecification: settings where the learner is fundamentally unable to replicate expert behavior everywhere. This is often true in practice due to differences in observation space and action space expressiveness (e.g. perceptual or morphological differences between robots and humans).

Identifying the sources of model misspecification

open access: yes, 2015
In this paper we propose an empirical method for detecting and identifying misspecification in structural economic models. Our approach formalizes the common practice of adding "shocks" in the model, and identifies potential misspecification via forecast

Dealing with Misspecification in DSGE Models: A Survey [PDF]

open access: yes, 2017
Dynamic Stochastic General Equilibrium (DSGE) models are the main tool used in Academia and in Central Banks to evaluate the business cycle for policy and forecasting analyses.

Simulating realistic patient profiles from pharmacokinetic models by a machine learning postprocessing correction of residual variability

open access: yesCPT: Pharmacometrics & Systems Pharmacology
We address the problem of model misspecification in population pharmacokinetics (PopPK), by modeling residual unexplained variability (RUV) by machine learning (ML) methods in a postprocessing step after conventional model building. The practical purpose

Errors in Statistical Inference Under Model Misspecification: Evidence, Hypothesis Testing, and AIC

open access: yesFrontiers in Ecology and Evolution, 2019
The methods for making statistical inferences in scientific analysis have diversified even within the frequentist branch of statistics, but comparison has been elusive.

Minimum Penalized ϕ-Divergence Estimation under Model Misspecification

open access: yesEntropy, 2018
This paper focuses on the consequences of assuming a wrong model for multinomial data when using minimum penalized ϕ -divergence, also known as minimum penalized disparity estimators, to estimate the model parameters.

Complexity and Misspecification

open access: yes
We propose a tractable model of repeated decision problems that combines concern about model misspecification, as in robust control, with a complexity cost, such as Shannon entropy, that makes pessimistic beliefs trade off statistical plausibility against simplicity. In a static setting, stronger complexity aversion selects more concentrated worst-case

Robust Portfolio Optimization with Environmental, Social, and Corporate Governance Preference

open access: yesRisks
This study addresses the crucial but under-explored topic of ambiguity aversion, i.e., model misspecification, in the area of environmental, social, and corporate governance (ESG) within portfolio decisions.
