WebQuite a few academicians & practitioners for a good reason believe that coarse classing results in loss of information. However, in my opinion, coarse classing has the following advantage over using raw measurement for a variable. 1. It reduces random noise that exists in raw variables – similar to averaging and yes, you lose some information ...

WebJul 7, 2024 · What is coarse classing? 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. http://aiecon.org/conference/2008/CIEF/Building%20a%20Scorecard%20in%20Practice.pdf

You want to keep this quite granular at this stage so you might have a large number of bins (perhaps up to 20). For example you could split a variable like property age into 5 yearly splits, so you’d have 0-5, 5-10 and so on with a bin at the end for ...

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
