Estimation and Model Misspecification for Recurrent Event Data with Covariates Under Measurement Errors

Mathematics
For subject i, we monitor an event that can occur multiple times over a random observation window [0, τi). At each recurrence, p concomitant variables, xi, associated to the event recurrence are recorded—a subset (q≤p) of which is measured with errors ...

Certainty equivalence and model uncertainty [PDF]

Simon’s and Theil’s certainty equivalence property justifies a convenient algorithm for solving dynamic programming problems with quadratic objectives and linear transition laws: first, optimize under perfect foresight, then substitute optimal forecasts ...

Multidimensional Scaling of the Cognitive Assessment System‐Second Edition: Implications for the Structural Validity of PASS Theory and Its Application in School Psychology

Psychology in the Schools, EarlyView.
ABSTRACT This study applied multidimensional scaling (MDS) to the Cognitive Assessment System‐Second Edition (CAS2) to investigate the structural validity of PASS theory (Planning, Attention, Simultaneous, Successive) across two age groups (5−7, 8−18 years) in the normative sample (N = 1342).

Speciation with gene flow

PLANTS, PEOPLE, PLANET, EarlyView.
Biodiversity is threatened by human activities, with extinction debt accumulating rapidly. Many of these activities change the connectivity of populations, fragmenting existing population systems or bringing previously isolated populations or species into contact.

Simulation-based inference with deep ensembles: evaluating calibration uncertainty and detecting model misspecification

Machine Learning: Science and Technology
Simulation-based inference (SBI) offers a principled and flexible framework for conducting Bayesian inference in any situation where forward simulations are feasible.

Undersmoothing Causal Estimators With Generative Trees

IEEE Access
Average causal effects are averages of (heterogeneous) individual treatment effects (ITEs) taken over the entire target population. The estimation of average causal effects has been studied in depth, but averages are insufficient for more individualised ...
