Some Applications of Watson's Perturbation Approach to Random Matrices


  • Ruymgaart, Frits H.
  • Yang, Song


In this note we draw attention to Watson's (1983) perturbation approach to random matrices, by which the asymptotic distribution of eigenvalues and eigenvectors can be derived in a very elegant way. We extend his result to functions of matrices and give some applications in principal component analysis, multivariate analysis, and canonical correlations.
