9. Linear Regression
? The analytic modelling used to predict the handle values is Linear
Regression .Since the handle is a continuous variable , this is the best
method to understand the predict the values.
? Following are the charts that show the results of the predicted values
and the error with respect to the original handle values .
? (The details of the variables used in the regression are in the Excel
files.)

18. Important Points
? The predicted values for the range upto handle = 700,000 is predicted
with a good accuracy.
? The model does not do a good job of predicting higher values of
handle.
? The Handle values vs error graph shows most of the values
symmetrically placed along the x axis , the error are random and
therefore there is not any collinearity issue.
? Adj R sq is in the range 0.60 – 0.75 for all the different analysis.
