High Quality Content by WIKIPEDIA articles! Analytica is a visual software package developed by Lumina Decision Systems for creating, analyzing and communicating quantitative decision models. Analytica includes hierarchical influence diagrams for visual creation and view of models, intelligent arrays for working with multidimensional data, and Monte Carlo simulation for analyzing risk and uncertainty. The design of Analytica, especially its influence diagrams and treatment of uncertainty, is based on ideas from the field of decision analysis. Analytica includes a computer language, which is notable in being declarative (non-procedural) for referential transparency, supporting array abstraction, and providing automatic dependency maintenance for efficient sequencing of computation.
