Scale likelihoods/rates (DTMC/CTMC) by the simulation time-step size.
The DEPM model stores individual transitions rates/likelihoods by step-length. But the number of steps are not scaled by clock time. Therefore, the rates/likelihoods are not representative of real time systems.
One way to solve is issue is to store all rates/likelihoods with a constant multiplier, which can be set at simulation time.
