TITULO: 

. "LINEAR GROUPING USING ORTHOGONAL REGRESSION"


ABSTRACT:

This paper proposes a new method, called linear grouping algorithm (LGA), to
detect different linear structures in a data set.
LGA is useful for investigating potential linear patterns in datasets, that
is, subsets that follow different linear relationships. LGA combines ideas
from principal components, clustering methods and resampling algorithms. It
can detect several different linear relations at once. We also propose
methods to determine the number of groups in the data and diagnostic tools
to investigate the results obtained from LGA. It is shown how LGA can be
extended to detect groups characterized by lower dimensional hyperplanes as
well.
Some applications illustrate the usefulness of LGA in practice.
