Low serum GP88 levels were more often detected in younger patients (≤66 years) and high levels in elder patients (>66 years; P =0.018; Fisher’s exact test). The Gleason scores (GS) of the PCa patients were ...
WebThe same result can be accomplished via so called Fisher linear classification functions which utilizes original features directly. However, Bayes' approach based on discriminants is a little bit general in that it will allow to use separate class discriminant covariance matrices too, in addition to the default way to use one, the pooled one.
