Qualifications and Experience
Cas Troskie was appointed to the
Department of Mathematics as UCTs first full time lecturer in statistics
in 1964, becoming Professor and Head of the newly-created Department of
Mathematical Statistics in 1966. He had previously worked at the
National Research Institute for Mathematical Sciences of the CSIR from
1957. He spent 1962 at the University of Columbia, New York, and has had
extended periods of research leave at the University of Gottingen, and
at Stanford University (1980 and 1986).
He obtained his BSc (1957) and MSc (1960)
from the University of Pretoria, and a PhD Regression applications of
multivariate distributions from UNISA in 1963.
He is a member of the South African
Statistical Association (President of the Association in 1972) and the
Operations Research Society of South Africa. He has served on the Joint
Matriculation Board, and its successor, the SA Certification Council, as
statistician since 1972, and on several regional Educational Councils.
He was, for many years, a member of the Advisory Panels of the Institute
for Biostatistics of the Medical Research Council and the National
Research Institute for Mathematical Sciences of the CSIR. He has been
chairman of the UCT Sports Council and has served on the South African
Universities Sports Council (1968-1988) and is a keen golfer.
Research Interests
His theoretical research interests lie in
multivariate analysis, particularly multivariate distribution theory and
the general linear model. Currently, he is developing tests for outliers
and influential observations in multivariate regression. This theory is
applied to the extensive econometric database built up within the
department. He has supervised 24 MSc and 14 PhD students.
