A recent asymptotic model of cascading failure in two-domain, coupled infrastructure systems is used to pose and solve a generic degree-distribution design problem. A low-order nonlinear analysis exposes the mechanisms by which optimized graphs can form star-like clusters, as embedded into specialized distributions. Several other design rules are developed. Through examples on coupled systems o...

In this manuscript we present various robust statistical methods popular in the social sciences, and show how to apply them in R using the WRS2 package available on CRAN. We elaborate on robust location measures, and present robust t-test and ANOVA versions for independent and dependent samples, including quantile ANOVA. Furthermore, we present on running interval smoothers as used in robust AN...

Data from a human feeding trial with healthy men were used to develop a dose-response model for 13 strains of Salmonella and to determine the effects of strain variation on the shape of the dose-response curve. Dose-response data for individual strains were fit to a three-phase linear model to determine minimum, median, and maximum illness doses, which were used to define Pert distributions in ...
