Linear discriminant analysis (LDA) was applied on these parameters to differentiate the opiate addicts included in MMTP or in detoxification treatment and the healthy subjects.

The paper develops optimality theory for linear discriminant analysis in the high dimensional setting. A data-driven and tuning-free classification rule, which is based on an adaptive constrained ...

High-dimensional classification is an important and challenging statistical problem. We develop a set of quadratic discriminant rules by simplifying the structure of the covariance matrices instead of ...
