For a stochastic quantal endpoint, this equals the expected population incidence of the quantal effect. This procedure was used for the stochastic quantal treatment of tumors with [10.sup.7] MC samples for uncertainty (j) (for [theta], [10.sup.3] bootstrap samples were resampled with replacement) and [10.sup.4] MC samples for variability (k).
However, not all quantal effects may be derived from applying a cut point to an underlying continuous variable.
In the context of quantal theories of C*, this means that the NSCP must not be based on non-local quantal effects. (Those who accept the non-locality of some superordinate cosmic C* will, of course, draw the opposite conclusion, but this is not the position of Emergent Dualism.)
