dc.description.abstract | Multivariate statistical analysis is the area of statistics that is concerned with observations made on many variables. Determining how variables are related is a main objective in multivariate analysis. The covariance matrix is an essential part of understanding the dependence between variables. The distribution of the sample covariance matrix for a sample from a multivariate normal distribution, known as the Wishart distribution, is fundamental to multivariate statistical analysis. An important assumption of the well-known Wishart distribution is that the number of variables is smaller than the number of observations. In high-dimensions when the number of variables exceeds the number of observations, the Wishart matrix is singular and has a singular Wishart distribution. The purpose of this research is to rederive the Wishart and singular Wishart distributions and understand the mathematics behind each derivation. | |
