High-dimensional tests for spherical location and spiked covariance
Rotationally symmetric distributions on the p -dimensional unit hypersphere, extremely popular in directional statistics, involve a location parameter θ that indicates the direction of the symmetry axis. The most classical way of addressing the spherical location problem H0 : θ = θ0 , with θ0 a fixed location, is the so-called Watson test, which is based on the sample mean of the observations. ...
متن کاملSparse Quadratic Discriminant Analysis For High Dimensional Data
Many contemporary studies involve the classification of a subject into two classes based on n observations of the p variables associated with the subject. Under the assumption that the variables are normally distributed, the well-known linear discriminant analysis (LDA) assumes a common covariance matrix over the two classes while the quadratic discriminant analysis (QDA) allows different covar...
متن کاملHigh Dimensional Discriminant Analysis
We propose a new method of discriminant analysis, called High Dimensional Discriminant Analysis (HHDA). Our approach is based on the assumption that high dimensional data live in different subspaces with low dimensionality. Thus, HDDA reduces the dimension for each class independently and regularizes class conditional covariance matrices in order to adapt the Gaussian framework to high dimensio...
متن کاملCovariance-enhanced discriminant analysis.
Linear discriminant analysis has been widely used to characterize or separate multiple classes via linear combinations of features. However, the high dimensionality of features from modern biological experiments defies traditional discriminant analysis techniques. Possible interfeature correlations present additional challenges and are often underused in modelling. In this paper, by incorporati...
متن کاملBayesian Quadratic Discriminant Analysis
Quadratic discriminant analysis is a common tool for classification, but estimation of the Gaussian parameters can be ill-posed. This paper contains theoretical and algorithmic contributions to Bayesian estimation for quadratic discriminant analysis. A distribution-based Bayesian classifier is derived using information geometry. Using a calculus of variations approach to define a functional Bre...
