This model illustrates the use of GoldSim's built-in optimization capability to carry out a calibration (by fittting a second-order equation to the historical Dow Jones average). The Time Series DJ_History represents the observed data. The simulated record is computed by Fit, and the error between the observations and the model is computed by RMS_Error (which is minimized by the optimizer). There are three optimization variables used to fit the model to the observations.
