Multivariate Statistical Methods
Early work on matrix derivatives [1, 45]. Since differentiation is a linear map, partial differentiation interfaces with matrix notation. This simplifies work in least squares and maximum likelihood estimation [3, 6, 7, 8, 10]. Some minor papers on the non-central F-distribution [27, 66] and the non-null distribution of intraclass correlations (which is central F). Intraclass correlations provide basic data for twin research ( see Quantitative Behavior Genetics, below).
