Using the Lambert function to estimate shared frailty models with a normally distributed random intercept Am. Stat. (IF 8.325) Pub Date : 2022-08-08 Hadrien Charvat
Abstract Shared frailty models, that is, hazard regression models for censored data including random effects acting multiplicatively on the hazard, are commonly used to analyze time-to-event data possessing a hierarchical structure. When the random effects are assumed to be normally distributed, the cluster-specific marginal likelihood has no closed-form expression. A powerful method for approximating

ABSTRACT Modern wearable monitors and laboratory equipment allow the recording of high-frequency data that can be used to quantify human movement. However, currently, data analysis approaches in these domains remain limited. This paper proposes a new framework to analyze biomechanical patterns in sport training data recorded across multiple training sessions using multilevel functional models. We apply

On arbitrarily underdispersed discrete distributions Am. Stat. (IF 8.325) Pub Date : 2022-07-26 Alan Huang
Abstract We survey a range of popular generalized count distributions, investigating which (if any) can be arbitrarily underdispersed, i.e., its variance can be arbitrarily small compared to its mean. A philosophical implication is that some models failing this simple criterion should not be considered as “statistical models” according to the extendibility criterion of McCullagh (2002). Four practical

Statistical Inference for Method of Moments Estimators of a Semi-Supervised Two-Component Mixture Model Am. Stat. (IF 8.325) Pub Date : 2022-06-30 Bradley Lubich, Daniel Jeske, Weixin Yao
Abstract A mixture of a distribution of responses from untreated patients and a shift of that distribution is a useful model for the responses from a group of treated patients. The mixture model accounts for the fact that not all the patients in the treated group will respond to the treatment and consequently their responses follow the same distribution as the responses from untreated patients.

A Comparison of Bayesian Multivariate Versus Univariate Normal Regression Models for Prediction Am. Stat. (IF 8.325) Pub Date : 2022-06-08 Xun Li, Joyee Ghosh, Gabriele Villarini
Abstract In many moderate dimensional applications we have multiple response variables that are associated with a common set of predictors. When the main objective is prediction of the response variables, a natural question is: do multivariate regression models that accommodate dependency among the response variables improve prediction compared to their univariate counterparts? Note that in this paper

Linearity of Unbiased Linear Model Estimators Am. Stat. (IF 8.325) Pub Date : 2022-05-11 Stephen Portnoy
Abstract Best linear unbiased estimators (BLUE’s) are known to be optimal in many respects under normal assumptions. Since variance minimization doesn’t depend on normality and unbiasedness is often considered reasonable, many statisticians have felt that BLUE’s ought to preform relatively well in some generality. The result here considers the general linear model and shows that any measurable estimator

Abstract Kaplan and Meier’s 1958 paper developed a nonparametric estimator of the survivor function from a right-censored data set. Determining the size of the support of the estimator as a function of the sample size provides a challenging exercise for students in an advanced course in mathematical statistics. We devise two algorithms for calculating the support size and calculate the associated probability

A New Transformation of Treated-Control Matched-Pair Differences for Graphical Display Am. Stat. (IF 8.325) Pub Date : 2022-04-11 Paul R. Rosenbaum
Abstract A new transformation is proposed for treated-minus-control matched pair differences that leaves the center of their distribution untouched, but symmetrically and smoothly transforms and shortens the tails. In this way, the center of the distribution is interpretable, undistorted and uncompressed, yet outliers are clear and distinct along the periphery. The transformation of pair differences

Inference in experiments conditional on observed imbalances in covariates* Am. Stat. (IF 8.325) Pub Date : 2022-03-23 Per Johansson, Mattias Nordin
Abstract Double blind randomized controlled trials are traditionally seen as the gold standard for causal inferences as the difference-in-means estimator is an unbiased estimator of the average treatment effect in the experiment. The fact that this estimator is unbiased over all possible randomizations does not, however, mean that any given estimate is close to the true treatment effect. Similarly

Expressing Regret: A Unified View of Credible Intervals Am. Stat. (IF 8.325) Pub Date : 2022-03-15 Kenneth Rice, Lingbo Ye
Abstract Posterior uncertainty is typically summarized as a credible interval, an interval in the parameter space that contains a fixed proportion—usually 95%—of the posterior’s support. For multivariate parameters, credible sets perform the same role. There are of course many potential 95% intervals from which to choose, yet even standard choices are rarely justified in any formal way. In this article

Coherent Tests for Interval Null Hypotheses Am. Stat. (IF 8.325) Pub Date : 2022-03-08 Spencer Hansen, Ken Rice
Abstract In a celebrated paper, Schervish [1996] showed that, for testing interval null hypotheses, tests typically viewed as optimal can be logically incoherent. Specifically, one may fail to reject a specific interval null, but nevertheless – testing at the same level with the same data – reject a larger null, in which the original one is nested. This result has been used to argue against the widespread

Abstract Evaluation of treatment effects and more general estimands is typically achieved via parametric modeling, which is unsatisfactory since model misspecification is likely. Data-adaptive model building (e.g., statistical/machine learning) is commonly employed to reduce the risk of misspecification. Naïve use of such methods, however, delivers estimators whose bias may shrink too slowly with sample

A statistical basis for reporting strength of evidence as pool reduction Am. Stat. (IF 8.325) Pub Date : 2022-01-10 Dan J. Spitzner
Abstract This article establishes a statistical basis for an evidence-reporting strategy that interprets strength of evidence in terms of a reduction in the size of a pool of relevant conceptual objects. The strategy is motivated by debates in forensic science, wherein the pool would consist of sources of forensic material. An advantage of using the pool-reduction strategy is that it highlights uncertainty
