/** 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.
