This process is analogous to performing an analysis of variance on continuous data, which can be performed by PROC CATMOD. If there are n nominal variables, rather than 1, then PROC CATMOD can do an n ...

A principal component analysis of a covariance matrix is equivalent to an analysis of a weighted correlation matrix, where the weight of each variable is equal to its variance. Variables with large ...

Homogeneity of variance is the assumption that your data sets are equal in variance. It allows for the validation of ...

Principal component analysis (PCA) is a mathematical algorithm ... we begin by looking at the proportion of the variance present in all genes contained within each principal component (Fig.
