title: 'cutpoint: Estimate Cutpoints of Metric Variables in the Context of Cox Regression'

  value: 10.32614/CRAN.package.cutpoint
abstract: Estimate one or two cutpoints of a metric or ordinal-scaled variable in
  the multivariable context of survival data or time-to-event data. Visualise the
  cutpoint estimation process using contour plots, index plots, and spline plots.
  It is also possible to estimate cutpoints based on the assumption of a U-shaped
  or inverted U-shaped relationship between the predictor and the hazard ratio. Govindarajulu,
  U., and Tarpey, T. (2022) <https://doi.org/10.1080/02664763.2020.1846690>.
