The interpolation weights used in smoothing (for combining higher and
lower-order estimates) do not have to be estimated separately from data.
They are a given by formulae derived from the counts-of-counts, and
built into the discounting methods.
If you are asking about interpolation different LMs, use
compute-best-mix, described in the ppl-scripts(1) man page.
