Core concepts in pharmacoepidemiology: Violations of the positivity assumption in the causal analysis of observational data: Consequences and statistical approaches
Sign Up to like & getrecommendations! Published in 2021 at "Pharmacoepidemiology and Drug Safety"
DOI: 10.1002/pds.5338
Abstract: In the causal analysis of observational data, the positivity assumption requires that all treatments of interest be observed in every patient subgroup. Violations of this assumption are indicated by nonoverlap in the data in the… read more here.

DOI: 10.1002/qj.3759
Abstract: Funding information Submitted on July 28, 2019 Revised onDecember 27, 2019 For tropical rainfall, there are several potential sources of predictability, including synoptic-scale convectively coupled equatorial waves (CCEWs) and intraseasonal oscillations such as theMadden–Julian Oscillation… read more here.

DOI: 10.1007/jhep03(2021)273
Abstract: We discuss deep learning inference for the neutron star equation of state (EoS) using the real observational data of the mass and the radius. We make a quantitative comparison between the conventional polynomial regression and… read more here.

DOI: 10.1016/j.cognition.2018.06.003
Abstract: Previous work suggests that humans find it difficult to learn the structure of causal systems given observational data alone. We identify two conditions that enable successful structure learning from observational data: people succeed if the… read more here.

DOI: 10.1016/j.fertnstert.2018.04.005
Abstract: Randomized clinical trials are considered the preferred approach for comparing the effects of treatments, yet data from high-quality clinical trials are often unavailable and many clinical decisions are made on the basis of evidence from… read more here.

DOI: 10.1016/j.prevetmed.2017.09.002
Abstract: The objective of this study was to illustrate the implementation of a mixed-model-based structural equation modeling (SEM) approach to observational data in the context of feedlot production systems. Different from traditional multiple-trait models, SEMs allow… read more here.

DOI: 10.1038/s41467-021-24149-x
Abstract: Empirical measurements of ecological networks such as food webs and mutualistic networks are often rich in structure but also noisy and error-prone, particularly for rare species for which observations are sparse. Focusing on the case… read more here.

DOI: 10.1080/00273171.2018.1528542
Abstract: Abstract Statistical methods to identify mis-specifications of linear regression models with respect to the direction of dependence (i.e. whether or better approximates the data-generating mechanism) have received considerable attention. Direction dependence analysis (DDA) constitutes such… read more here.
