Multi Vari Analysis

Multi Vari Analysis - a powerful graphical analysis technique used to identify and quantify dominant sources of variation in a process. It is appropriate when the response variable (y) is continuous and the x's under investigation are discrete. Multi-Vari Analysis graphically depicts multiple sources of variation. It allows the examination of major families of variation, including positional (within unit or part), cyclical (unit-to-unit or part-to-part) and temporal (over time). The basic objective of Multi-Vari Analysis is to determine which family exhibits the largest variation.
