The third approach is to run Risk Simulator’s Multi-Variable Distributional Fitting Tool, and the resulting correlation matrix will be computed and displayed. It is important to note that correlation does not imply causation. , sunspot activity and events in the stock market are correlated, but there is no causation between the two). There are two general types of correlations: parametric and nonparametric correlations. Pearson’s correlation coefficient is the most common correlation measure and usually is referred to simply as the correlation coefficient.

25 shows another spider chart where nonlinearities are fairly evident (the lines on the graph are not straight but curved). The example model used is Tornado and Sensitivity Charts (Nonlinear), which applies the Black-Scholes option pricing model. 24 Tornado chart into the model’s dynamics. For instance, in this Black-Scholes model, the fact that stock price and strike price are nonlinearly related to the option value is important to know. This characteristic implies that option value will not increase or decrease proportionally to the changes in stock or strike price and that there might be some interactions between these two prices as well as other variables.

In more complex models, as is often the case in real-life situations, the effects will be unknown a priori and can be determined only after a simulation is run. 18 illustrates the results after running a simulation, extracting the raw data of the assumptions, and computing the correlations between the variables. 9 correlations and the resulting simulated values have the same correlations. Clearly there will be minor differences from one simulation run to another, but when enough trials are run, the resulting recovered correlations approach those that were inputted.
