To Decide Which Factor has the Highest Influence on the Results

[joonyeen]

Hi all,

Currently solving another problem, determining the influence of each given factor to check which has the highest influence. Objective of this is to eliminate factors which do not influence the outcome so greatly and can be forego to save cost and time.

any idea which test or which graph would be best to portray such results?

thanks,

You have many options to choose from. Here are three:

Perform a DOE (Designed Experiment) and display the main effects and interactions on an Effect Pareto chart (Minitab). This ranks the effects by strength and shows a line for significance of the effect.

Perform a Multi-Vari Study and graph the results stratified by the various factors to illustrate the relative effects.

A lesser known method used in Statistical Engineering is called a Diagnostic Tree. While this is not a Fault Tree Analysis, there are striking similarities. The Tree documents the potential sources of the Dominant Cause and the process of elimination used to narrow the search and identify the Dominant Cause.

Are you familiar with multiple regression analysis? I think its one of the best tool for this purpose. A small program called 'Lindo' is normally used.
