Natural-vs-treated fate delta for a taphonomic decay chain — morie_taphonomy_decay

The Markov-chain analogue of the preservation "delta": the change in the probability of ending "mummified" when a preservation factor (e.g. quicklime) is applied, relative to the natural preservation = 0 baseline. A large positive delta means the burial practice – not chance – drives the preserved outcome.

Usage

morie_taphonomy_decay_delta(preservation, start = NULL, ...)

Arguments

preservation: Preservation factor in (0, 1] for the treated chain.
start: Starting transient stage (default the first).
...: Passed to morie_taphonomy_decay_chain (decay_rate, mummify_rate, states).

Value

A named list (all double): p_mummified_natural, p_mummified_treated, delta, and a plain-language interpretation.
