A high migration rate of a population causes the number of a country’s residents to become extremely volatile, which negatively affects the quality of population frames. The aim of the paper is to present a method for estimating the number of residents included in a study population frame. The...

We provide a new definition of breakdown in finite samples with an extension to asymptotic breakdown. Previous definitions center around defining a critical region for either the parameter or the objective function. If for a particular outlier constellation the critical region is entered,...

This paper proposes new, simple, and more accurate statistical tests in a cointegrated system that allows for endogenous regressors and serially dependent errors. The approach involves first transforming the time series using some orthonormal basis functions in L2[0,1], which has energy...
