Quantum XL 2009 includes numerous new features including more flexible model building, latitude plots, percent contribution plots, support for 13 distributions, and much more.
Quantum XL supports multiple model building methods.
Model Building - Quantum XL includes several ways to build models. The article on Simple Monte Carlo Analysis using Quantum XL gives you the key facts to run Monte Carlo simulations quickly.
Latitude Plots are a visual representation of the expected variation region vs. the available latitude window. Below are the links to a series of five articles to help you understand and create these powerful plots.
Part I - Understanding Latitude Plots
Part II - Understanding Latitude Plots
Part III - Interpreting Latitude Plots
Part IV - Multiple Inputs and Latitude Plots
