After each iteration, consider the stopping guidelines: Stopping guidelines: Define U r to be the uncertainty for the optimal collapse at iteration r. The stopping decision may be based on the percentage change in U r between iterations: PC r = (U r-1 - U r) / U r-1 lake appraisal

Coarse classing is where a binning process is applied to the fine granular bins to merge those with similar risk and create fewer bins, usually up to ten. The purpose is to achieve simplicity by creating fewer bins, each with distinctively different risk factors, while minimizing information loss.
