Popis: | In this article scan statistics for detecting a local change in variance for two dimensional normal data are discussed. When the precise size of the rectangular window where a local change in variance has occurred is unknown, multiple and variable window scan statistics are proposed. A simulation study is presented to evaluate the performance of the scan statistics investigated in this article via comparison of power. A method for estimating the rectangular region where a change in variance has occurred and the size of the change in variance is also discussed. |
