Model prediction. (a) Comparison of measured alumina strength exiting calcination (red line) with stepwise regression strength model (black line). The data to the left of the vertical blue line is used to construct the model. The curves to right of the blue line show the predictive power of the model. (b) Plot of measured strength against stepwise regression model, where the black, magenta and red points correspond to the training set, testing set and predicted values, respectively. Strength values are not included in graphs due to confidentiality concerns.
