Timeline
Georg William Rasch (21 September 1901 – 19 October 1980) was a Danish mathematician, statistician, and psychometrician, most famous for the development of a class of measurement models known as Rasch models.
In 1919, Rasch began studying mathematics at the University of Copenhagen.
He completed a master's degree in 1925 and received a doctorate in science with thesis director Niels Erik Nørlund in 1930.
Unable to find work as a mathematician in the 1930s, he turned to work as a statistical consultant.
In this capacity, he worked on a range of problems, including problems of biological growth.
Georg Rasch is best known for his contributions to psychometrics.
His work in this field began when he used the Poisson distribution to model the number of errors made by students when reading texts.
He referred to the model as the multiplicative Poisson model.
He later developed the Rasch model for dichotomous data, which he applied to response data derived from intelligence and attainment tests including data collected by the Danish military.
At the same epoch, American scientists independently developed item response theory (IRT).
Within IRT, the Rasch model is one of the most simple response models.
In contrast to other simple models, the Rasch model has a distinctive mathematical property: the model parameters (item difficulties, examinee ability) are sufficient statistics.
Rasch demonstrated that his approach met criteria for measurement deduced from an analysis of measurement in the physical sciences.
He studied with R.A. Fisher and also briefly with Ragnar Frisch, and was elected a member of the International Statistical Institute in 1948.
He also proposed generalizations of his model (Rasch, 1960/1980, 1977).
Today, the Rasch model is used extensively in assessment in education and educational psychology, particularly for attainment and cognitive assessments.
Probabilistic models for some intelligence and attainment tests.
