st: New version of -bspline- on SSC

Thanks as always to Kit Baum, a new version of the -bspline- package is now available for download from SSC. In Stata, use the -ssc- command to do this, or -adoupdate- if you already have an old version of -bspline-.

The -bspline- package is described as below on my website. The new version has been updated to Stata Version 10 (from Stata Version 6), and therefore has .sthlp help files written in SMCL (as well as more up-to-date code in the .ado files).

Users of Stata Versions 6 to 9 can still download the old Stata Version 6 version from my website by typing

net describe bspline, from(http://www.imperial.ac.uk/nhli/r.newson/stata6)

and then installing the package.

Best wishes

Roger

TITLE
      bspline: Create a basis of B-splines or reference splines

DESCRIPTION/AUTHOR(S)
      The bspline package contains the programs bspline and frencurv, which
      generate bases of splines in an X-variable for inclusion in the
      design matrix of a regression model. The program bspline generates a
      basis of Schoenberg B-splines. The program frencurv ("French curve")
      generates a basis of reference splines, spanning the same spline
      space as the corresponding B-splines, but the fitted parameters
      in the regression model corresponding to the reference splines are
      simply values of the spline at reference points on the X-axis.
      These parameters are easy for non-mathematicians to understand.
      The user is allowed to specify the power of the spline, and also the
      positions of the knots and/or reference points.
      Full documentation of the program (including Methods and Formulas)
      can be found in the ancillary file bspline.pdf, which can be viewed
      using the Adobe Acrobat Reader.
