Thanks to all who advised to use -colelms-. It solves my problem.

It probably isn't LSM that you are looking for, and not the 1972 paper
either. Help for -zbmicat- (SJ) indicates the correct reference to the
1992 paper involving the LMS smoother.

For Cole's LMS smoother, try -colelms- (SSC) by Zhiqiang Wang & Mark Pearce:

ssc install colelms
h colelms

To every ω-consistent recursive class κ of formulae there correspond
recursive class signs r, such that neither v Gen r nor Neg(v Gen r)
belongs to Flg(κ) (where v is the free variable of r).
