Bootstrap confidence sets under model misspecification [PDF]

open access: yes, 2014
A multiplier bootstrap procedure for construction of likelihood-based confidence sets is considered for finite samples and a possible model misspecification.

Modeling Nonnegativity Via Truncated Logistic and Normal Distributions: An Application to Ranch Land Price Analysis

open access: yesJournal of Agricultural and Resource Economics, 1994
This study presents an empirical method of modeling the nonnegativity of dependent variables using truncated logistic and normal disturbance distributions. The method is applied in estimating a ranch land hedonic price function.

On model selection and model misspecification in causal inference [PDF]

open access: yesStatistical Methods in Medical Research, 2010
Standard variable selection procedures, primarily developed for the construction of outcome prediction models, are routinely applied when assessing exposure effects in observational studies. We argue that this tradition is sub-optimal and prone to yield bias in exposure effect estimators as well as their corresponding uncertainty estimators.

The Impact of Model-Misspecification on Model Based Personalised Dosing [PDF]

open access: yes, 2016
Model Based Personalised Dosing (MBPD) requires a population pharmacokinetic (PK) or pharmacodynamic model to determine the optimal dose of medication for an individual.

Comparing the Robustness of the Structural after Measurement (SAM) Approach to Structural Equation Modeling (SEM) against Local Model Misspecifications with Alternative Estimation Approaches

open access: yesStats, 2022
Structural equation models (SEM), or confirmatory factor analysis as a special case, contain model parameters at the measurement part and the structural part.

Specifying Turning Point in Piecewise Growth Curve Models: Challenges and Solutions

open access: yesFrontiers in Applied Mathematics and Statistics, 2017
Piecewise growth curve model (PGCM) is often used when the underlying growth process is not linear and is hypothesized to consist of phasic developments connected by turning points (or knots or change points).

On the pitfalls of Gaussian likelihood scoring for causal discovery

open access: yesJournal of Causal Inference, 2023
We consider likelihood score-based methods for causal discovery in structural causal models. In particular, we focus on Gaussian scoring and analyze the effect of model misspecification in terms of non-Gaussian error distribution. We present a surprising

Market selection and learning under model misspecification [PDF]

open access: yes, 2023
This paper studies market selection in an Arrow-Debreu economy with complete markets where agents learn over misspecified models. Under model misspecification, standard Bayesian learning loses its formal justification and biased learning processes may ...

Robust Online Control with Model Misspecification

open access: yesCoRR, 2021
We study online control of an unknown nonlinear dynamical system that is approximated by a time-invariant linear system with model misspecification. Our study focuses on robustness, a measure of how much deviation from the assumed linear approximation can be tolerated by a controller while maintaining finite $\ell_2$-gain.
