Hi, I hope some one can help. I need to compute Thurston's case 5 on a large set of data. I have gotten as far as computing the proportional preference matrix but the next math is beyond me.
Here us my matrix 0.500 0.472 0.486 0.587 0.366 0.483 0.496 0.434 0.528 0.500 0.708 0.578 0.633 0.554 0.395 0.620 0.514 0.292 0.500 0.370 0.557 0.580 0.615 0.329 0.413 0.422 0.630 0.500 0.783 0.641 0.731 0.663 0.634 0.367 0.443 0.217 0.500 0.351 0.907 0.686 0.517 0.446 0.420 0.359 0.649 0.500 0.325 0.559 0.504 0.605 0.385 0.269 0.093 0.675 0.500 0.625 0.566 0.380 0.671 0.337 0.314 0.441 0.375 0.500 Can someone help me write an R script to compute the Thurston Case 5 values? The result should be the scale values for each item. I found three web pages that might be useful in this, but again, I didn't know enough to translate them into a result. http://marketing.byu.edu/htmlpages/books/pcmds/THURSTONE.html http://www.personality-project.org/r/thurstone.html http://en.wikipedia.org/wiki/Law_of_comparative_judgment Thanks, Jared -- View this message in context: http://www.nabble.com/thurston-case-5-tp21768835p21768835.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
