Kenichi Satoh (Japan), Hirokazu Yanagihara (Japan) and Megu Ohtaki (Japan)
|
Abstract: A
clustering method by connected neighborhoods
is proposed. Some theoretical properties are
derived and the concept is applied to a
weighted estimation in order to highlight the
major structure of the distribution. Numerical
study showed good performance of the
estimation for the case when there exist some
outliers under the normal distribution and the
simple regression model. |
Keywords and phrases: clustering, neighborhood, weighted estimation, outliers. |
