  This article shows how to specify and construct a discrete, stochastic,
continuous-time model specifically for ecological systems. The model is more
broad than typical chemical kinetics models in two ways. First, using
time-dependent hazard rates simplifies the process of making models more
faithful. Second, the state of the system includes individual traits and use of
environmental resources. The models defined here focus on taking survival
analysis of observations in the field and using the measured hazard rates to
generate simulations which match exactly what was measured.
