st: New version of the -bspline- package on SSC

[Roger Newson <roger.newson@kcl.ac.uk>]

Fellow Statalisters

Thanks to Kit Baum (again), there is a new version of the -bspline- package 
available for download on SSC. In Stata, type -ssc desc bspline- to find 
out more, or see below.

The -bspline- package creates bases of B-splines or reference splines. The 
new version contains the same program as before, but now has a .pdf manual, 
including Methods and Formulas, and a help file that refers the user to the 
manual.

Best wishes

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.
