Estimation Under Model Misspecification With Fake Features

open access: yesIEEE Transactions on Signal Processing, 2023
We consider estimation under model misspecification where there is a model mismatch between the underlying system, which generates the data, and the model used during estimation. We propose a model misspecification framework which enables a joint treatment of the model misspecification types of having fake features as well as incorrect covariance ...

Making Decisions under Model Misspecification [PDF]

open access: yesSSRN Electronic Journal, 2020
Abstract We use decision theory to confront uncertainty that is sufficiently broad to incorporate “models as approximations.” We presume the existence of a featured collection of what we call “structured models” that have explicit substantive motivations.

An improved multiply robust estimator for the average treatment effect

open access: yesBMC Medical Research Methodology, 2023
Background In observational studies, double robust or multiply robust (MR) approaches provide more protection from model misspecification than the inverse probability weighting and g-computation for estimating the average treatment effect (ATE). However,

Model misspecification [PDF]

open access: yesStatistical Modelling, 2008
A common problem in statistical modelling is to distinguish between finite mixture distribution and a homogeneous non-mixture distribution. Finite mixture models are widely used in practice and often mixtures of normal densities are indistinguishable from homogenous non-normal densities.

Model Misspecification as the Causes of Flypaper Effect

open access: yesProceedings, 2023
The aim of this paper is to investigate the relationship between the Fly-paper effect (FPE) and possible errors in the specification of econometric models used in the empirical analysis of FPE.

Effect of Probability Distribution of the Response Variable in Optimal Experimental Design with Applications in Medicine

open access: yesMathematics, 2021
In optimal experimental design theory it is usually assumed that the response variable follows a normal distribution with constant variance. However, some works assume other probability distributions based on additional information or practitioner’s ...

Likelihood-based estimation and prediction for a measles outbreak in Samoa

open access: yesInfectious Disease Modelling, 2023
Prediction of the progression of an infectious disease outbreak is important for planning and coordinating a response. Differential equations are often used to model an epidemic outbreak's behaviour but are challenging to parameterise. Furthermore, these

Minimizing sensitivity to model misspecification [PDF]

open access: yesQuantitative Economics, 2018
We propose a framework for estimation and inference when the model may be misspecified. We rely on a local asymptotic approach where the degree of misspecification is indexed by the sample size. We construct estimators whose mean squared error is minimax in a neighborhood of the reference model, based on one‐step adjustments.
