Discretizing Unobserved Heterogeneity [PDF]
SSRN Electronic Journal, 2017 We study discrete panel data methods where unobserved heterogeneity is revealed in a first step, in environments where population heterogeneity is not discrete. We focus on two‐step grouped fixed‐effects (GFE) estimators, where individuals are first classified into groups using kmeans clustering, and the model is then ...

Unobserved heterogeneity in auctions [PDF]
The Econometrics Journal, 2018 A common concern in the empirical study of auctions is the likely presence of auction-specific factors that are common knowledge among bidders but unobserved to the econometrician. Such unobserved heterogeneity confounds attempts to uncover the underlying structure of demand and information, typically a primary feature of interest in an auction market.

Reported MPC and Unobserved Heterogeneity
American Economic Journal: Economic Policy, 2020 Panel data on reported marginal propensity to consume in the 2010 and 2016 Italian Survey of Household Income and Wealth uncover a strong negative relationship between cash on hand and MPC. Even though the relationship is attenuated when using regression methods that control for unobserved heterogeneity, the amount of bias is moderate.

Demographic Research, 2014 Background: Statistical theory predicts that failing to control for unobserved heterogeneity in a Gompertz mortality risk model attenuates the estimated income-mortality gradient toward zero. Objective: I assess the empirical importance of controlling

Modelling Unobserved Heterogeneity in Claim Counts Using Finite Mixture Models
Risks, 2020 When modelling insurance claim count data, the actuary often observes overdispersion and an excess of zeros that may be caused by unobserved heterogeneity.

Unobserved population heterogeneity: A review of formal relationships
Demographic Research, 2014 Background: Survival models accounting for unobserved heterogeneity (frailty models) play an importantrole in mortality research, yet there is no article that concisely summarizes useful relationships.

The unobserved heterogeneity distribution in duration analysis [PDF]
Biometrika, 2006 In a large class of hazard models with proportional unobserved heterogeneity, the distribution of the heterogeneity among survivors converges to a gamma distribution. This convergence is often rapid. We derive this result as a general result for exponential mixtures and explore its implications for the specification and empirical analysis of univariate

Bayesian heterogeneous assembly time modeling for robotic performance prediction
Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2021 Robotic systems are widely applied in manufacturing industry to reduce labor cost and increase productivity. Due to the influence of different observed factors (e.g., controllable robotic settings) and the unobserved heterogeneity caused by the ...

Unobserved Heterogeneity in Hospitality and Tourism Research [PDF]
Journal of Travel Research, 2015 Despite the growing complexity of structural equation model (SEM) applications in tourism, it is surprising that most applications have estimated these models without accounting for unobserved heterogeneity. In this article, we aim to discuss the concept of unobserved heterogeneity in more detail, highlighting its serious threats to the validity and ...
