You could definitely pick one of the PDAL dimensions to be used as the
samples in your fit step. They are simply returned as numpy ndarrays, so
scipy should be able to work with them. Also, the earlier provided iPython
notebook was a reader-only pipeline, but you could make that pipeline as
complex as you like (it sounds like you have at least some PCL stages, for
example). Another example (different packages, but same idea) is provided
at https://gist.github.com/chambbj/efa93860aa316f607ea4b3215395f627.
