The mean of the observations from a given category (also called center of gravity, center of mass, mean vector, or centroid)

Confidence interval

An interval encompassing a given proportion (e.g., 95%) of an estimate of a parameter (e.g., a mean)

Discriminant analysis

A technique whose goal is to assign observations to some predetermined categories

Discriminant factor scores

A linear combination of the variables of a data matrix. Used to assign observations to categories

Design matrix (aka group matrix)

In a group matrix, the rows represent observations and the columns represent a set of exclusive groups (i.e., an observation belongs to one and only one group). A value of 1 at the intersection of a row and a column indicates that the observation represented by the row belongs to the group represented by the column. A value of 0 at the intersection of a row and a column indicates that the...
