Inheritance diagram for mvpa.mappers.zscore:
Simple mapper to perform zscoring
Bases: mvpa.mappers.base.ProjectionMapper
Mapper to project data into standardized values (z-scores).
After the mapper has been instantiated, it has to be train first.
Since it tries to reuse ProjectionMapper, invariant features will simply be assigned a std == 1, which would be equivalent to not standardizing them at all. This is similar to not touching them at all, so similar to what zscore function currently does
Initialize ZScoreMapper
