Announcements

• final exam solutions are avaliable.
• I goofed on my solutions to HW6. The last kappa and polychoric correlation was wrong, since I split the table incorrectly. Sorry. Corrected version is up now. Make sure you clear your cache before you redownload. John kolassa.
• I've updated the sas input and output for l11 to include polychoric correlation calculation information. This might be useful for HW6.
• I've got a couple of sample questions for the final.
• Exam 1 solutions
• I think that there's an error in Table 1 of the notes of lecture 1. My evaluation of the exact confidence intervals had an error in it. Sorry about that. This is fixed in the current version on line.
• I've got a sample exam and another practice exam solutions available.

Prerequisites

Other resources

• Introductions to sas and R are available.
• The death penalty data, the purity data, the oesophageal cancer data, the Copenhagen housing data, the eyesight data, the lottery data, the prostate data, and the falls data for one of the homeworks.
• Other data sets can be found on the statlib web site.
• The British government statistical website.
• The source code for the MLLSA program for latent class analysis is available. You might also want the precomplied PC version; even if you don't use this, you can rip out the example input file, as I did. The results I presented can be repeated by downloading a gziped tar file , unzipping and untarring it, changing to the directory that it creates, and typing "auto". This will automatically download the source code, and the PC archive with the examples, edit the source code and the example file, configure and edit the code, and run the program.
• If you have a hard time reading the pdf files I put up, and are using Windows, you might try downloading gs5.50, a postscript reader that will also read pdf.
