Uses the empirical probability distribution (puts mass $$1/n$$ on each of the observations, or uses weights if specified) to estimate a marginal density. Inherits from LF_base; see that page for documentation on likelihood factors in general. Only compatible with marginal likelihoods (no parent nodes). Only compatible with densities (no conditional means). The type argument will be ignored if specified.
