Previous research investigating sketching processes during object visualisation and design has indicated that drawing occurs in a primarily part-bypart manner, whereby the component volumetric structures of objects appear to dominate the organisation of ongoing activity. Some non-part-by-part...

Adaptive two-stage designs allow a data-driven change of design characteristics during the ongoing trial. One of the available options is an adaptive choice of the test statistic for the second stage of the trial based on the results of the interim analysis. Since there is often only a vague...

This paper considers the problem of estimation when one of a number of populations, assumed normal with known common variance, is selected on the basis of it having the largest observed mean. Conditional on selection of the population, the observed mean is a biased estimate of the true mean....
