The last section, VBA Reference - Public Functions, lists the public functions available in VBA. The next section, VBA Reference - Public Variables, lists the public variables available in VBA. Two tables give a summary listing of available variables and functions.
EXCEL VBA LATIN HYPERCUBE SAMPLING HOW TO
Organization The first section, Overview, details how to use the VBA functions and variables, how to specify settings, and how to run simulations from VBA. For example, you may wish to run multiple simulations, one after another, and compare the results between each. The second category of functions and types allows you to start and control an simulation and get simulation results. Or perhaps you want to make a custom settings interface, which shields other users from certain details.

You can see that the LHS chart is a much smoother curve (and better represents the classic S-curve of the normal distribution).Guide to VBA Macro Language Risk Analysis and Simulation Add-In for Microsoft Excel ® The chart on the right uses Latin Hypercube Sampling. The chart on the left uses standard random number generation. Both include 100 samples (to start with). A visual manifestation of the reduced-form approach is programmed in Excel-VBA. Uncertainties are presented as CDF and RFD. Behavioral effects and economic resilience are considered. The charts below are sampling from a normal distribution. Synthetic data from Latin Hypercube sampling with Monte Carlo randomization is used. For complex models with many random variables, this means you can generate results in less time.

In practice, this can be used to generate “better” simulation results, with lower standard error levels, with fewer trials. For two samples, it will divide the sample space in two, and generate one sample from each side. LHS will always return one sample less than 0 and one sample greater than 0.
EXCEL VBA LATIN HYPERCUBE SAMPLING GENERATOR
Although the probability of being positive or negative is equal, a true random number generator might return two samples less than 0, or two samples greater than 0. Latin Hypercube Sampling (LHS) is a method of sampling random numbers that attempts to distribute samples evenly over the sample space.Ī simple example: imagine you are generating exactly two samples from a normal distribution, with a mean of 0.
