Abstract Inference for the parameters indexing generalised linear models is routinely based on assumption that model correct and a priori specified. This unsatisfactory because chosen usually result of data-adaptive selection process, which may induce excess uncertainty not acknowledged. Moreover, assumptions encoded in rarely represent some known, ground truth, making standard inferences prone...

In the Performance-Based Engineering (PBE) framework, uncertainties in system parameters, or modelling uncertainties, have been shown to significant effects on capacity fragilities and annual collapse rates of buildings. Yet, since are non-ergodic variables, their consideration failure rate calculations offends Poisson assumption independent crossings. This problem has addressed literature, err...

A finite group $G$ is called rational if all its irreducible complex characters are rational valued. In this paper we discuss about rational groups with Sylow 2-subgroups of nilpotency class at most 2 by imposing the solvability and nonsolvability assumption on $G$ and also via nilpotency and nonnilpotency assumption of $G$.
