Simplicity Above Elegance: Another Look at the Asymptotically Correct Standardization of Snijders
Abstract
Person-fit statistics are widely used to detect aberrant response patterns in educational and psychological measurement. Snijders suggested an asymptotically correct standardization for a broad class of such statistics. This paper presents an alternative derivation of this standardization. The derivation yields several advantages including a simpler formula and simpler description of several person-fit statistics including the l z * statistic and a theoretical explanation of simulation findings reported by Snijders and van Krimpen-Stoop and Meijer, among others.
