1) Canonical correlation analysis (CCA) is a statistical method that analyzes the correlation relationship between two sets of multidimensional variables.
2) CCA finds linear transformations of the two sets of variables so that their correlation is maximized. This can be formulated as a generalized eigenvalue problem.
3) The number of dimensions of the transformed variables is determined using Bartlett's test, which tests the eigenvalues against a chi-squared distribution.

It has become essential to use literature databases as previously known information in bioscience studies. This lecture provides the overview and some actual usage examples of some databases including PubMed of NIH in US, and KEGG of Kyoto University Institute for Chemical Research.
This document discusses metabolic network analysis and summarizes information from the KEGG database. It describes searching metabolic terms on Google and Google Scholar, keywords used in metabolic network analysis, and basic concepts in metabolic network reconstruction. It also provides an overview of the KEGG PATHWAY, MEDICUS, Mapper, and Expression databases and tools for mapping gene expression data onto metabolic pathways. The document concludes by assigning a report task analyzing gene expression data mapped to pathways using KEGG Expression and KegArray.
