Some exercises to go with Bock & Bargmann: 1) Port the Case I problem R to (your choice of) S-plus or Matlab or Gauss or SAS, and report interesting features and/or comparative speed? 2) Do the Case I problem with (your choice of) Lisrel or M-plus or EQS or Calis or whatever, and report interesting features and/or comparative speed (if that can be determined)? 3) Do one of B&Bıs other numerical examples?
