Various alternatives for the design of clonal field trials in forestry were studied using simulated data to identify “optimal” or “near-optimal” scenarios for the estimation of genetic parameters. The simulated field site consisted of a rectangular grid on which 256 clones with 8 ramets each were installed. Estimates of genetic parameters were compared for (1) single-tree and four-tree row plot...

In his 1923 landmark article, Neyman introduced randomization-based inference to estimate average treatment effects from experiments under the completely randomized design. Under this framework, Neyman considered the statistical estimation of the sample average treatment effect and derived the variance of the standard estimator using the treatment assignment mechanism as the sole basis of infer...

Object-oriented languages provide powerful programming features such as polymorphism, inheritance, and dynamic dispatch. While these features allow complex programs to be written more easily, they also make debugging and understanding these programs more di cult. Object-oriented languages have relied on simple visualization tools such as class browsers to aid programmers in understanding their ...
