WebJan 14, 2024 · A deterministic model will always produce the same output for a given set of inputs, while a stochastic model will produce varying outputs due to random fluctuations. While both types of models have the capability to make predictions about future events, the assumptions and level of certainty they incorporate set them apart. http://egon.cheme.cmu.edu/ewo/docs/SnyderEWO_081113.pdf
