Optimal Designs For the Restricted Maximum Likelihood Estimators in a Random Split-Plot Model

open access: yesLithuanian Journal of Statistics, 2017
The design effect for the restricted maximum likelihood estimators of variance components in acompletely randomized split-plot model is studied. The model was used to represent the response generated froman experimental scenario where the whole-plot and

Optimising trial designs to identify appropriate antibiotic treatment durations

open access: yesBMC Medicine, 2019
Background For many infectious conditions, the optimal antibiotic course length remains unclear. The estimation of course length must consider the important trade-off between maximising short- and long-term efficacy and minimising antibiotic resistance ...

Optimal designs of the median run length based double sampling X chart for minimizing the average sample size. [PDF]

open access: yesPLoS ONE, 2013
Designs of the double sampling (DS) X chart are traditionally based on the average run length (ARL) criterion. However, the shape of the run length distribution changes with the process mean shifts, ranging from highly skewed when the process is in ...
