Bayesian Latent-Normal Inference for the Rank Sum Test, the Signed Rank Test, and Spearman's $\rho$

  title={Bayesian Latent-Normal Inference for the Rank Sum Test, the Signed Rank Test, and Spearman's \$\rho\$},
  author={Johnny van Doorn and Alexander Ly and Maarten Marsman and Eric-Jan Wagenmakers},
  journal={arXiv: Methodology},
Bayesian inference for rank-order problems is frustrated by the absence of an explicit likelihood function. This hurdle can be overcome by assuming a latent normal representation that is consistent with the ordinal information in the data: the observed ranks are conceptualized as an impoverished reflection of an underlying continuous scale, and inference concerns the parameters that govern the latent representation. We apply this generic data-augmentation method to obtain Bayesian counterparts…

Using Bayes factor hypothesis testing in neuroscience to establish evidence of absence

Why P values do not differentiate inconclusive null findings from those that provide important evidence for the absence of an effect is shown and a tutorial on how to use Bayesian hypothesis testing to overcome this issue is provided.

Bayesian Frequentists: Examining the Paradox Between What Researchers Can Conclude Versus What They Want to Conclude From Statistical Results

Results show the expected discrepancy between what researchers think they can conclude from NHST and what they want to be able to conclude and to what extent researchers want to incorporate prior study results and their personal beliefs in their statistical inference.

The JASP guidelines for conducting and reporting a Bayesian analysis

These guidelines are geared towards analyses performed with the open-source statistical software JASP, and most guidelines extend to Bayesian inference in general.

Laypeople Can Predict Which Social Science Studies Replicate

Large-scale collaborative projects recently demonstrated that several key findings from the social-science literature could not be replicated successfully. Here we assess the extent to which a

Similarities and differences in spatial and non-spatial cognitive maps

The results support the notion that value-guided learning and generalization recruit cognitive-map dependent computational mechanisms in spatial and conceptual domains and find evidence for the same computational mechanisms of generalization across domains.

Searching for Rewards Like a Child Means Less Generalization and More Directed Exploration

Building a predictive model of search to disentangle the unique contributions of the three hypotheses of developmental differences, robust and recoverable parameter estimates are found indicating that children generalize less and rely on directed exploration more than adults.

Generalization guides human exploration in vast decision spaces

Modelling how humans search for rewards under limited search horizons finds evidence that Gaussian process function learning—combined with an optimistic upper confidence bound sampling strategy—provides a robust account of how people use generalization to guide search.

Exploration and generalization in vast spaces

A Bayesian function learning model, combined with an optimistic sampling strategy, robustly captures how humans use generalization to guide search behaviour, providing novel insights into the nature of human search in vast spaces.

Older adults sacrifice response speed to preserve multisensory integration performance

Modelling the within-trial dynamics of multisensory evidence accumulation reveals that older observers preserve audiovisual localisation performance by sacrificing response speed.

Extending the rank likelihood for semiparametric copula estimation

Quantitative studies in many fields involve the analysis of multivariate data of diverse types, including measurements that we may consider binary, ordinal and continuous. One approach to the

Informed Bayesian t-Tests

A flexible t-prior for standardized effect size is proposed that allows computation of the Bayes factor by evaluating a single numerical integral and two measures for informed prior distributions that quantify the departure from the objective Bayes factors desiderata of predictive matching and information consistency are proposed.

The Efficiency of Some Nonparametric Competitors of the t-Test

Consider samples from continuous distributions F(x) and F(x — θ). We may test the hypothesis θ = 0 by using the two-sample Wilcoxon test. We show in Section 1 that its asymptotic Pitman efficiency,

For this large class of priors, it is shown that the (marginal) posterior for Pearson's correlation coefficient and all of the posterior moments are analytic.

Bayesian estimation of the polychoric correlation coefficient

The problem of estimating a polychoric correlation coefficient from a latent bivariate normal distribution is considered from a Bayesian viewpoint. Using the Gibbs sampling algorithm, one can

Abstract A vast literature in statistics, biometrics, and econometrics is concerned with the analysis of binary and polychotomous response data. The classical approach fits a categorical response

To facilitate use of the Bayes factor, an easy-to-use, Web-based program is provided that performs the necessary calculations and has better properties than other methods of inference that have been advocated in the psychological literature.
