near remapping 
scheme is the default and approximates the thickness distribution in each 
category as a linear function ((<A
 HREF="node40.html#lips01">Lipscomb(2001)</A>)).  The delta function method 
represents <I>g(h)</I> in each category as a delta function ((<A
 HREF="node40.html#bitz01">Bitz et&nbsp;al.(2001)</A>)).  
This method can leave some categories mostly empty at any given time and cause 
jumps in the properties of <I>g(h)</I>.
