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

Australian &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 ...

How data or error covariance can change and still retain BLUEs as well as their covariance or the sum of squares of errors

Australian &New Zealand Journal of Statistics, EarlyView.
Summary Misspecification of the error covariance in linear models usually leads to incorrect inference and conclusions. We consider two linear models, A$$ \mathcal{A} $$ and B$$ \mathcal{B} $$, with the same design matrix but different error covariance matrices. The conditions under which every representation of the best linear unbiased estimator (BLUE)

Profiles of control, value and achievement emotions in primary school mathematics lessons

British Journal of Educational Psychology, EarlyView.
Abstract Background Achievement emotions are important for mathematical achievement. However, it is currently unclear how specific combinations of emotions—and their associated control and value appraisals—relate to mathematics performance, especially in younger students.
