Sampling Distributions in VBA CodeĪpplies to: 5.0 and newer, Professional and Industrial Editions If you are creating a custom application in VBA, you can easily create an instance of a Distribution object, with the properties of any of these probability distributions.10.4. These distributions are available to you through the Risk Solver Ribbon dropdown galleries, through new Excel functions with the names listed below, or through Risk Solver's VBA Object Model. And you can specify shifting and truncation to customize your probability distributions. Risk Solver Engine provides both a complete set of analytic probability distributions, and a complete set of methods for defining custom distributions, both discrete and continuous, by supplying sample data or by specifying certain parameters. With the PsiSeed() property function, you can create a separate random number stream for a specific distribution, such as a Certified Distribution.
In many cases the effect is too small to make a difference - but in some cases, found in financial engineering and other demanding applications, better results are obtained if independent random number sequences (streams) are used for each distribution in the model. Most Monte Carlo simulation tools generate a single sequence of random numbers, which introduces a subtle dependence between the samples for all distributions in one trial. Risk Solver offers multiple streams of random numbers. For low to moderate dimensional problems, Sobol numbers offer the "best of both worlds" - the speed of Standard Monte Carlo with the "coverage" of Latin Hypercube sampling. They are widely used by developers in quantitative finance.
Sobol numbers - generated with a random shift for "Randomized Quasi Monte Carlo" - are an innovation in Risk Solver that's not found in other risk analysis product for Excel. Latin Hypercube sampling is a well-known method for reducing sample variance, enabling you to obtain more accurate simulation results with fewer Monte Carlo trials. Risk Solver Engine can generate Monte Carlo samples from a wide range of probability distributions, using any of three methods: Standard Monte Carlo, Latin Hypercube, and Sobol numbers.

Random numbers form the basis of Monte Carlo simulation - you need to know that simulation software uses the best random number generation algorithms. In fact, Risk Solver gives you more choices for random number generation, more sampling methods, and more analytic distributions than other risk analysis products for Excel. You don't give up any power to gain Risk Solver's ease and speed of use.
