Regression analysis The regression models have shown a correlation between the answers and specific process variables, including the weight percentage of reinforcement (n-B 4 C), applied load, and sliding speed. The regression equations are constructed using the significance of the parameters obtained from the ANOVA. The generated model's suitability for both responses is confirmed by the validation exercise. After modifying the built model to include the anticipated sets of process variables, the response obtained for both outputs is contrasted with experimental values obtained for the same set of parameters. The relevant equations for regression for both are given in Eqns. 2 and 3 below.
