Your goal this week is to define regression analysis and highlight the various factors that you need to consider with regression analysis. For example, what is a R-square and when would you be able to use regression to help forecast cost. Be sure to discuss times that you could see regression as a tool for estimating and when you think regression would not be a good tool for estimating. Also, see if you can provide alternative analysis techniques that may be used when estimating future cost using historical analysis—- what analysis might you use to forecast cost when historical actuals do not exist?
