Confidence intervals

Confidence intervals can be used to evaluate if a model is "close enough" to a system for some variable of interest. The difference between the known model value, μ, and the system value, μ, is checked to see if it is less than a value small enough that the model is valid with respect that variable of interest. The value is denoted by the symbol ε. To perform the test a number, n, statistically independent runs of the model are conducted and a mean or expected value, E(Y) or μ for simulation output variable of interest Y, with a standard deviation S is produced. A confidence level is selected, 100(1-α). An interval,, is constructed by
