I'm looking for the data resampling part where the data gets moved & interpolated to a time boundary. There's section in Alex's tutorial at the end called "Data Resampling". I want the math. I studied math through differentiable manifolds, but my statistics knowledge is very poor. Andy Ford A.G. Edwards & Sons Technology Group, Inc.
