For a randomized treatment setting,\nthe functions assess and test for heterogeneity using both a\nparametric model and a semiparametric two-step model. More\ndetails for the randomized setting are available in: Knowlton,\nR., Tian, L., & Parast, L. (2025). \"A General Framework to\nAssess Complex Heterogeneity in the Strength of a Surrogate\nMarker,\" Statistics in Medicine, 44(5), e70001\n. For an observational setting,\nfunctions in this package assess complex heterogeneity in the\nstrength of a surrogate marker using meta-learners, with\noptions for different base learners. More details for the\nobservational setting will be available in the future in:\nKnowlton, R., Parast, L. (2025) \"Assessing Surrogate\nHeterogeneity in Real World Data Using Meta-Learners.\" A\ntutorial for this package can be found at\n.", "License": "GPL", "NeedsCompilation": "no", "Packaged": {
