Abstract

rc_spline creates variables that can be used for regression models in which the linear predictor f(xvar) is assumed to equal a restricted cubic spline function of an independent variable xvar. In these regressions, the user explicitly or implicitly specifies k knots located at xvar = t1, t2, ..., tk. f(xvar) is defined to be a continuous smooth function that is linear before t1, is a piecewise cubic polynomial between adjacent knots, and is linear after tk. See Harrell (2001) for additional details.
