A test of uniformity on shape spaces

Journal of Multivariate Analysis, 2004, vol. 88, issue 1, 163-176

Abstract: A test of uniformity on the shape space [Sigma]mk is presented, together with modifications of the test statistic which bring its null distribution close to the large-sample asymptotic distribution. The asymptotic distribution under suitable local alternatives to uniformity is given. A family of distributions on [Sigma]mk is proposed, which is suitable for modelling shapes given by landmarks which are almost collinear.
