Timeline for When sampling a population for surveys we can often limit our sample size to hundreds, but when doing a Monte Carlo simulation we need way more. Why?

That is, if the objective of a procedure is to arrive at an answer that is precise to within a few percent, then that objective is not the same as testing whether A or B is more explanatory of C. The lesson is to first identify the objective of a test, and only thereafter worry about sample size to guarantee power. | |

Where is it written that you can, or might want to extend that to Monte Carlo simulations, of a multi-parameter model or not? How is any simulation thought of as representing a sample of the larger population of all possible simulations (the solution space) related to the Question or its exposition? The solution space of a multi-dimensional problem can be very large, and how does the survey/poll scenario tell you that doesn’t mean the sample size will need to be large. | |
| Oct 24, 2022 at 5:19 | comment | added | Jyrki Lahtonen | What are the relative probabilities? Top performance often means a low probability of failure, and to get even one significant digit into the outcome of a simple Bernoulli trial you need to run the sim until you get 200 failure events or so. Personally I had to battle with this when working in telcomm, and the target quality of service was bit error probability in the ball park of $10^{-12}$ or so (I would run "quick Monte Carlo" sims pitting competing suggestions down to $10^{-9}$ and expecting the trend on the error curves as a function of SNR to continue). | |
