SLAW is a procedure that derives representative scaling laws of a process from sensitivity analysis experimental data. The approach integrates dimensional analysis into the multivariate linear regression backwards elimination procedure. In addition to the scaling laws, the program provides a set of dimensionless groups ranked by relevance. The algorithm is coded in 6 Matlab .m files and also has a java interface.
