This directory contains Mx scripts corresponding to the LISREL scripts found in the Appendices from the Neale & Cardon "Methodology for Genetic Studies on Twins and Families" 1992 book (Kluwer Academic Publishers). The files mxe.tex, mxe.dvi, mxe.ps are latex, dvi and postscript files with the examples laid out in the same format as they are in the manual, from appendix A to K. Otherwise, the file names are supposed to be reasonably intuitive.
