On the diversity of test instances for studying branch‐and‐bound performance

open access: yesAustralian &New Zealand Journal of Statistics, EarlyView.
Summary In their paper ‘An Automatic Method for Solving Discrete Programming Problems’, Ailsa Land and Alison Doig developed a branch‐and‐bound method for solving the general case of the mixed integer linear programming (MIP) problem. A core part of the algorithm, branch variable selection, has received renewed attention in recent years with the ...

The stratigraphic biography of an archaeological site. Timing depositional events

open access: yesArchaeometry, EarlyView.
Abstract The stratigraphic sequence of an archaeological site constitutes its biography, which details what was deposited, when it was deposited, and how the deposition occurred. However, many current methods of recording archaeological stratigraphy do not allow for a full reconstruction of a site's biography.

Optimizing calibration designs with uncertainty in abilities

open access: yesBritish Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract Before items can be implemented in a test, the item characteristics need to be calibrated through pretesting. To achieve high‐quality tests, it's crucial to maximize the precision of estimates obtained during item calibration. Higher precision can be attained if calibration items are allocated to examinees based on their individual abilities ...

Multi‐response phylogenetic mixed models: concepts and application

open access: yesBiological Reviews, EarlyView.
ABSTRACT The scale and resolution of trait databases and molecular phylogenies is increasing rapidly. These resources permit many open questions in comparative biology to be addressed with the right statistical tools. Multi‐response (MR) phylogenetic mixed models (PMMs) offer great potential for multivariate analyses of trait evolution.
