Detailed Description

A class for containing arbitrary multi-dimensional feature data.

A number of fields are defined in the EST_FeatureData class, each of which represents a measurable quantity, such as height, age or gender. Any number of fields can be defined and each field can take a float, integer or string value. The class holds multiple instances of field values, representing samples taken from a population.

Several statistical training, testing and analysis programs use EST_FeatureData as input and output. Member functions exist for comparing fields, extracting given named or numbered fields, can converting appropriate fields to a EST_FMatrix.
