We use the rand() function to return a random number as our probability and feed it into the inverse normal probability function to generate a value. Two numbers drawn from a normal distribution are our inputs and the output is their product. In order to keep things simple the model I will be demonstrating these techniques on will be supper simple. When I say lots of times I mean thousands, perhaps hundreds of thousands or even millions of times. The important part is that we have to run our model lots of times with new draws for the variables. For a more extensive discussion of this method check out the Wikipedia article HERE. But there is a degree of uncertainty around these estimates, by drawing values from each of the distributions multiple times we can determine likely outcomes. We know that almost every input to our models are just point estimates. To put it simply the Monte Carlo method is taking a bunch of guesses for your inputs and seeing what all of your results look like. What is it, how can I get started using it? Well just follow after the jump to find out. On the secure Digital River page, specify quantity (number of licenses).Today we are going to talk about a more advanced topic in model evaluation.

SimVoi automates the simulation by trying thousands of what-ifs consistent with your assessment of the uncertainties and displays the results in histograms, cumulative charts, bivariate scatter plots, and value of information charts. You can use simulation to determine the uncertainty associated with the model’s output (e.g., annual profit). Examples are demand for a new product, uncertain variable cost of production, and competitor reaction. Your spreadsheet model may include various uncontrollable uncertainties as input assumptions. SimVoi provides random number generator functions as inputs for your model, automates Monte Carlo simulation, computes value of information, and displays the results.
