Implements simple\nslopes analysis following Aiken and West (1991,\nISBN:9780761907121), Johnson-Neyman intervals following Johnson\nand Fay (1950) and Bauer and Curran\n(2005) , and grand- or\ngroup-mean centering as described in Enders and Tofighi (2007)\n. Includes a slope variance\ndecomposition that separates fixed-effect uncertainty from\nrandom-slope variance (tau11), a contour surface plot of\npredicted outcomes over the full predictor-by-moderator space,\nand robustness diagnostics comprising intraclass correlation\ncoefficient shift analysis and leave-one-cluster-out (LOCO)\nstability checks. Designed for researchers in education,\npsychology, biostatistics, epidemiology, organizational\nscience, and other fields where outcomes are clustered within\nhigher-level units.", "License": "MIT +
