    Deciding by RMSE how many simulation results to use for a representative sample

    So, I'm doing a brute force Monte Carlo simulation to vary certain parameters and running a model through a thermal computational test bed. At the end I get temperatures for every hour. We have field data of the actual temperatures, so I do a RMSE to decide which parameters best fit the actual...
