Generate a linear spline transformation of a variable          [STB18: sg24]
-----------------------------------------------------

	^lspline^ varname stem [nodelist] [^if^ exp] [^in^ range]
		[^, nodetype replace]

generates a set of new variables that comprise a linear spline transformation
of varname.  The spline variables begin with the characters in the stem and 
are numbered sequentially from 1.


Options
-------

^nodetype^ specifies automatic node choice.  The choice is one of ^mean^,
^median^, or ^quartile^.  You must either enter a nodelist or a nodetype.

^replace^ indicates that ^lspline^ can replace any variable that has the
same name as one of the generated spline variables.
