The Exploration of Effect of Model Misspecification and Development of an Adequacy-Test for Substitution Model in Phylogenetics [PDF]
, 2012 It is possible that the maximum likelihood method can give an inconsistent result when the DNA sequences are generated under a tree topology which is in the Felsentein Zone and analyzed with a misspeci ed model.

Imputation Estimators Partially Correct for Model Misspecification [PDF]
, 2011 Inference problems with incomplete observations often aim at estimating population prop-erties of unobserved quantities. One simple way to accomplish this estimation is to impute the unobserved quantities of interest at the individual level and then take

Welfare Cost of Model Uncertainty in a Small Open Economy
Entropy, 2020 This paper extends the canonical small open-economy real-business-cycle model, when considering model uncertainty. Domestic households have multiplier preferences, which leads them to take robust decisions in response to possible model misspecification ...

Model Misspecification in Statistical Analysis [PDF]
, 2017 In my talk, I will discuss two important problems related with model misspecification. How do we provide powerful tests for checking misspecification in hypothesized models?

Agribusiness, EarlyView.ABSTRACT Using survey and discrete choice experiment data, we examined US specialty crop growers' preferences for marketing contract attributes in the context of emerging blockchain‐based technologies and expanding traceability initiatives. Results show that farmers preferred traditional written contracts but might be willing to accept digital ...

System Misspecification Testing and Structural Change in the Demand for Meats
Journal of Agricultural and Resource Economics, 1995 A misspecification testing strategy designed to ensure that the statistical assumptions underlying a system of equations are appropriate is outlined. The system tests take into account information in, and interactions between, all equations in the system

On the consequences of model misspecification in logistic regression. [PDF]
Environmental Health Perspectives, 1990 Logistic regression models are commonly used to study the association between a binary response variable and an exposure variable. Besides the exposure of interest, other covariates are frequently included in the fitted model in order to control for their effects on outcome.

Accounting for animal health in efficiency analysis: An application to Swedish dairy farms
American Journal of Agricultural Economics, EarlyView.Abstract Poor animal health is a central concern in modern livestock production. Despite the necessity to incorporate animal health in efficiency analysis, the theoretical and empirical developments are limited on this subject. This article appropriately characterizes the axiomatic properties of animal health within a production framework.

Generalized Information Matrix Tests for Detecting Model Misspecification
Econometrics, 2016 Generalized Information Matrix Tests (GIMTs) have recently been used for detecting the presence of misspecification in regression models in both randomized controlled trials and observational studies.
