Abstract:
|
The analysis of a fixed number of multivariate individual observations for step shifts in the statistical distribution of the observations, possibly combined with multiple outliers, depends on an accurate estimate of the covariance matrix. This research offers a method for partitioning the observations so that within each part the observations are homogeneous while adjacent parts have statistically significantly different mean vectors.
