Hi, netlanders. I am doing some research in which we want to compute guttman scale values of some 70 variables. I know that SAS has a procedure called "proc guttman" but it allows me to include only 12 variables. This is too a restriction for us. Thus, I am exploring the possibility of writing a program using either c or perl that allows me to include more than 70 variables in computing the guttman scaling algorithm. I'd like to do it on my pc or on a unix computer. If any of you have an algorithm that computes guttman scale values for a large number of variables, can you please share your algorithm with me? If any of you have heard of a book, a person, or a anonymous ftp site, or whatever, could you please be kind enough to point me to the person, book, etc. Thanks a lot, Min P.S. BTW, please e-mail me at soh3@midway.uchicago.edu.
