The general public considers Fixed-Route Transit (FRT) to be inconvenientwhile Demand-Responsive Transit (DRT) provides much of the desired flexibility with adoor-to-door type of service. However, FRT is typically more cost efficient than DRT todeploy. Therefore, there is an increased interest...

Stepped wedge randomised trials are increasingly popular. Here we derive the optimal design for a fixed number of periods; this does not allocate an equal number of cluster units to each treatment sequence as might otherwise have been expected.

Measurement on sets with a specific geometric shape can be of interest for many important applications (e.g., measurement along the isotherms in structural engineering). The properties of optimal designs for estimating the parameters of shifted Ornstein–Uhlenbeck sheets are investigated when...

Classical regression analysis is usually performed in two steps. In a first step an appropriate model is identified to describe the data generating process and in a second step statistical inference is performed in the identified model. An intuitively appealing approach to the design of...
