There are no such examples in the practice files. However, there are
examples of use of the mle command in the Gretl User's Guide and I
presume that use of mle would be the preferred way of estimating a
threshold model. You just need the loglikelihood function for the
model you want to estimate.
Perhaps it's even simpler than that, depending on what's meant with
threshold regression here: If the threshold is known, you can just
create a dummy variable defined as (x>threshold) and interact that
dummy with x.
