http://idisk.mac.com/jdeleeuw-Public/jacobi This is paper/software for various techniques based on Jacobi plane rotations. There is R code for -- classical cyclical Jacobi Eigen diagonalization -- Jacobi-based SVD diagonalization -- approximate simultaneous diagonalization of symmetric matrices (De Leeuw/Pruzansky 1978) -- approximate simultaneous diagonalization of rectangular matrices (TUCKER-2) -- approximate body diagonalization of three-way arrays (orthogonal INDSCAL) -- TUCKER-3 for three-way arrays (three rotations meet a core) -- PREHOM/MCA approximate KPL-diagonalization of the Burt matrix (De Leeuw/Bekker 1982) =========================================================Jan de Leeuw, 11667 Steinhoff Rd, Frazier Park, CA 93225 home 661-245-1725 skype 661-347-0667 global 254-381-4905 .mac: jdeleeuw +++ aim: deleeuwjan +++ skype: j_deleeuw ========================================================= Many nights on the road and not dead yet --- the end of autumn.
