Overview

About

Maintained by Zhiqiang NieFirst published 2022-10-103 releasesCRAN page ↗GitHub ↗

Restricted Cubic Splines were performed to explore the shape of association form of "U, inverted U, L" shape and test linearity or non-linearity base on "Cox,Logistic,linear,quasipoisson" regression, and auto output Restricted Cubic Splines figures. rcssci package could automatically draw RCS graphics with Y-axis "OR,HR,RR,beta". The Restricted Cubic Splines method were based on Suli Huang (2022) doi:10.1016/j.ecoenv.2022.113183,Amit Kaura (2019) doi:10.1136/bmj.l6055, and Harrell Jr (2015, ISBN:978-3-319-19424-0 (Print) 978-3-319-19425-7 (Online)).
