Hi Virgil,

Check Johannes Ludsteck's package, it may fulfill your needs:

http://library.wolfram.com/infocenter/MathSource/5161/

"This Mathematica 5.0 Package performs nonparametric spline smoothing 
for time series (called the Hodrick-Prescott-Filter in the econometrics 
literature). In addition to other implementations, the optimum smoothing 
parameter of the model is computed for a stochastic formulation of the 
data generating process."

Hope this helps,
