TL;DR: In this article, the authors present a brief tutorial for estimating, testing, fit, and interpretation of ordinal and binary outcomes using Stata. But they do not discuss how to apply these models to other estimation commands, such as post-estimation analysis.

TL;DR: A joint (multi-phenotype) analysis of educational attainment and three related cognitive phenotypes generates polygenic scores that explain 11–13% of the variance ineducational attainment and 7–10% ofthe variance in cognitive performance, which substantially increases the utility ofpolygenic scores as tools in research.

TL;DR: A growing body of evidence suggests that transparency, openness, and reproducibility are vital features of science as discussed by the authors, and most scientists embrace these features as disciplinary norms and values when asked, therefore, one might expect that these valued features would be routine in daily practice.

TL;DR: This paper conducted two studies of how experimental treatment effects obtained from convenience samples compare to effects produced by population samples and concluded that the utility of convenience samples can be justified by the similarity of treatment effects between convenience and nationally representative population-based samples.

TL;DR: This article investigated the extent to which MTurk samples differ from population samples, and the underlying nature of these differences by replicating items from the population-based American National Election Studies (ANES) 2012 Time Series Study in a survey administered to a sample of mTurk respondents.
