If users have a number of independent variables and wish to find the best combination among them, B-Box™ recommends the optimal model via “All Possible Models” method. It considers all possible combinations of the independent variables and provides the optimal model whose all regression coefficients are valid and AIC is minimum.
Also B-Box™ calculates residuals and detects outliers, as a result of which users possibly increase the model accuracy.

Moreover, silhouette scores are produced for each case, enabling you to see the changes in the silhouette scores when the clusters change, making it very convenient for you to run simulations to find suitable clusters.
