  "Description": "A major challenge in estimating treatment decision rules\nfrom a randomized clinical trial dataset with covariates\nmeasured at baseline lies in detecting relatively small\ntreatment effect modification-related variability (i.e., the\ntreatment-by-covariates interaction effects on treatment\noutcomes) against a relatively large non-treatment-related\nvariability (i.e., the main effects of covariates on treatment\noutcomes). The class of Single-Index Models with Multiple-Links\nis a novel single-index model specifically designed to estimate\na single-index (a linear combination) of the covariates\nassociated with the treatment effect modification-related\nvariability, while allowing a nonlinear association with the\ntreatment outcomes via flexible link functions. The models\nprovide a flexible regression approach to developing treatment\ndecision rules based on patients' data measured at baseline. We\nrefer to Park, Petkova, Tarpey, and Ogden (2020)\n<doi:10.1016/j.jspi.2019.05.008> and Park, Petkova, Tarpey, and\nOgden (2020) <doi:10.1111/biom.13320> (that allows an\nunspecified X main effect) for detail of the method. The main\nfunction of this package is simml().",
