R2-GenOpt*

Context

• R2-GenOpt* is one of the Automatic Discretization algorithms for Continuous variables in Step 4 — Discretization and Aggregation of the Data Import Wizard.

• R2-GenOpt* is a modified version of R2-GenOpt and uses a specific MDL score to choose the number of bins.

Algorithm Details & Recommendations

With 100 observations, even though we selected 8 bins, only 3 were created for the variable 8- Wrist girth.

With 1,500 observations, even though we selected 10 bins, only 5 have been created for AGN, and 6 for ALL.
