The complete set of recursions (equations (3), (5),
(4), (7), (9)), along with the
initializations, is formulated in the sketch of the general LSL algorithm
at the end of the paper (appendix A). As in any recursive method, we have
access to the residuals for all intermediate lengths of the prediction filter.
The basic concept is that a residual at time T is computed from the
minimization problem on the window [0,T], and does not depend on future
data, which is a first way to make the algorithm adaptive. The second way
is to introduce an exponential tapering, which forces the algorithm to forget
the ``old data''.
