Causally Regularized Learning with Agnostic Data Selection Bias
, 2018 Most of previous machine learning algorithms are proposed based on the i.i.d. hypothesis. However, this ideal assumption is often violated in real applications, where selection bias may arise between training and testing process.

Young children's referent selection is guided by novelty for both words and actions [PDF]
, 2016 Young children are biased to select novel, name-unknown objects as referents of novel labels (e.g., Markman, 1990) and similarly favour novel, action-unknown objects as referents of novel actions (Riggs, Mather, Hyde & Simpson, 2015).

Response to “Selection bias” [PDF]
Canadian Medical Association Journal, 2017 We thank Dr. Jansz[1][1] for his interest in our surveillance report.[2][2] We recognize that understanding the intricacies of the CanTravNet data would be difficult without first-hand experience of our network and its patient population. CanTravNet is a consortium of post-travel (not pretravel)

Methods in causal inference. Part 3: measurement error and external validity threats
Evolutionary Human SciencesThe human sciences should seek generalisations wherever possible. For ethical and scientific reasons, it is desirable to sample more broadly than ‘Western, educated, industrialised, rich, and democratic’ (WEIRD) societies. However, restricting the target

Network experiment designs for inferring causal effects under interference
Frontiers in Big Data, 2023 Current approaches to A/B testing in networks focus on limiting interference, the concern that treatment effects can “spill over” from treatment nodes to control nodes and lead to biased causal effect estimation. In the presence of interference, two main

Confidence intervals and P-valves for meta analysis with publication bias [PDF]
, 2006 We study publication bias in meta analysis by supposing there is a population (y, σ) of studies which give treatment effect estimates y ~ N(θ, σ2). A selection function describes the probability that each study is selected for review.

Risk of selection bias due to non-participation in a cohort study on pubertal timing. [PDF]
, 2020 BackgroundNon-participation in aetiologic studies of pubertal timing is frequent. However, little effort has been given to explore the risk and potential impact of selection bias in studies of pubertal timing.ObjectiveWe aimed to explore the risk of ...

A Proxy Bidding Mechanism that Elicits all Bids in an English Clock Auction Experiment [PDF]
, 2005 This paper reconsiders experimental tests of the English clock auction. We point out why the standard procedure can only use a small subset of all bids, which gives rise to a selection bias.
