Multiple Choice

A. deterministic because all model parameters are known with certainty, and the output of the model is fully determined by the model parameters

B. deterministic because some randomness is incorporated in the model; therefore, the model will produce different outputs even with the same inputs

C. stochastic because all model parameters are known with certainty, and the output of the model is fully determined by the model parameters

D. stochastic because some randomness is incorporated in the model; therefore, the model will produce different outputs even with the same inputs
