st: New version of -bspline- on SSC

["Roger B. Newson" <r.newson@imperial.ac.uk>]

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 still has the same programs, but the on-line help, and the 
manual -bspline.pdf- distributed with the package as an ancillary file, 
have been tidied up and updated.

Best wishes

Roger

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

DESCRIPTION/AUTHOR(S)
      The bspline package contains 3 commands, bspline, frencurv
      and flexcurv.  bspline generates a basis of B-splines in the
      X-variate based on a list of knots, for use in the design
      matrix of a regression model.  frencurv generates a basis of
      reference splines, for use in the design matrix of a
      regression model, with the property that the parameters
      fitted will be values of the spline at a list of reference
      points.  flexcurv is an easy-to-use version of frencurv, and
      generates reference splines with regularly-spaced knots, or
      with knots interpolated between the reference points.
      frencurv and flexcurv have the additional option of
      generating an incomplete basis of reference splines, which
      can be completed by the addition of the standard constant
      variable used in regression models.  The splines are either
      given the names in the newvarlist (if present), or (more
      usually) generated as a list of numbered variables, prefixed
      by the generate() option.  Usually (but not always), the
      regression command is called using the noconst option.
