D-optimal designs are derived in the complete block design set-up for comparing treatments using ordinary least squares estimators when the experimental errors are correlated. It is shown that the ...

Complete heart block means that there’s a complete separation of electrical activity between the upper and lower chambers of the heart. Without prompt medical attention, it can be fatal. Your heart ...

For a given block size, replication, and number of treatments, it is well known that a balanced incomplete block design, if one exists, is of maximum efficiency. We take the case of an even number of ...
