Fit assessment and selection between competitive models in sem
Statistica, 2007 This paper outlines some issues in fit assessment and in selection between competitive models in Structural Equation Models(SEM). The theory on chi-square statistic and the results of some simulation studies are reviewed and the methodological ...

British Journal of Clinical Pharmacology, EarlyView.Aim A prior non‐randomized study suggests that potassium supplementation may improve survival among furosemide initiators, and a randomized trial suggests that salt substitutes containing potassium might lower stroke risk. We conducted a retrospective cohort study using health‐care data to confirm or refute these associations among new users of ...

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

Business Strategy and the Environment, EarlyView.ABSTRACT Although ESG controversies are on the rise, research investigating them yields contradictory findings. The paper provides resolutions to the debate through investigating (a) how ESG controversies influence firms' short‐term and long‐term financial performance; (b) how firms navigate ESG controversies' effect; and (c) how ESG controversies ...

Prediction and Variable Selection in High-Dimensional Misspecified Binary Classification
Entropy, 2020 In this paper, we consider prediction and variable selection in the misspecified binary classification models under the high-dimensional scenario. We focus on two approaches to classification, which are computationally efficient, but lead to model ...

Interactions of age-dependent mortality and selectivity functions in age-based stock assessment models [PDF]
, 2011 The natural mortality rate (M) of fish varies with size and age, although it is often assumed to be constant in stock assessments. Misspecification of M may bias important assessment quantities.

Regression Based Expected Shortfall Backtesting
, 2019 This paper introduces novel backtests for the risk measure Expected Shortfall (ES) following the testing idea of Mincer and Zarnowitz (1969). Estimating a regression framework for the ES stand-alone is infeasible, and thus, our tests are based on a joint
