%description
An implementation of a single-index regression for optimizing
individualized dose rules from an observational study. To model
interaction effects between baseline covariates and a treatment variable
defined on a continuum, we employ two-dimensional penalized spline
regression on an index-treatment domain, where the index is defined as a
linear combination of the covariates (a single-index). An unspecified main
effect for the covariates is allowed, which can also be modeled through a
parametric model. A unique contribution of this work is in the
parsimonious single-index parametrization specifically defined for the
interaction effect term. We refer to Park, Petkova, Tarpey, and Ogden
(2020) <doi:10.1111/biom.13320> (for the case of a discrete treatment) and
Park, Petkova, Tarpey, and Ogden (2021) "A single-index model with a
surface-link for optimizing individualized dose rules"
<arXiv:2006.00267v2> for detail of the method. The model can take a member
of the exponential family as a response variable and can also take an
ordinal categorical response. The main function of this package is
simsl().
