There is a continuing interplay between mathematics and survey methodology involving different branches of mathematics, not only probability. This interplay is quite obvious as regards the first of the two options: probability vs. non-probability sampling, as proposed and discussed in Kalton...

The eigenproblem solution of the multi-domain efficient allocation is identified as a direct generalization of the classical Neyman-Tchuprov optimal allocation in stratified SRSWOR. This is achieved through analysis of eigenvalues and eigenvectors of a suitable population-based matrix D. Such...

Problems of specifying bivariate discrete distributions by a conditional distribution and a regression function are investigated. A review of the known results, together with new characterizations involving conditional power series laws, is given. Also some remarks on a method making use of...
