Statistics

The Department of Mathematical Sciences has a small active group of
statisticians. Their interests are in the theory and applications of statistics.
Specific research interests include nonparametric correlation and regression,
logistic regression and applications, applications of statistics in ecology
and natural resource economics, spatial statistics, and discriminant analysis.
A general interest statistics seminar meets weekly. Recent topics include
bootstrapping, generalized linear models, general statistical techniques
using a nonparametric correlation coefficient, SPlus, and spatial statistical
methods. Each year the department offers courses at the
junior, senior and graduate levels for majors as well as many services courses for nonmajors at
all levels. These courses cover mathematical and applied statistics and
statistical inference at beginning and advanced levels, computer data analysis,
nonparametric statistics, linear models, sampling methods, experimental
design, time series and other special topics. Use of computers is an integral
component in nearly all statistics courses. Software available includes
Data Desk, SPlus, SPSS, Mathematica and Maple. The department has 2 PC
labs, and a departmental network with Unix workstations.
