"Routines for Logspline Density Estimation")
(description
"Contains routines for logspline density estimation. The function
@code{oldlogspline()} uses the same algorithm as the logspline package version
1.0.x; i.e. the Kooperberg and Stone (1992) algorithm (with an improved
interface). The recommended routine @code{logspline()} uses an algorithm from
@url{doi:10.1214/aos/1031594728,Stone et al (1997)}.")
