Type I error rate for two-sample tests in statistical shape analysis

Abstract

Nowadays, with the help of advanced imaging techniques the image or shape of an organ or organism can be used as input data. Therefore, the statistical analysis of shape has recently become more important in the medical and biological sciences. Methods related to two-sample tests have been developed for statistical shape analysis, giving rise to considerable interest in research that evaluates the performance of these tests. In this study, two sample procedures are used to compare the mean shapes from the statistical shape analysis literature according to type I error rate.
