Glossary
- Barycenter:
-
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...
