The optimal structure of pd buckets
Web3.4 PD Bucket Bootstrapping Methodology If we build models based upon given, fixed PD bucket definitions, we may encounter the issue of a low firm-count for certain Sector/PD buckets. To achieve the dual-goal of having granularity and obtaining accurate model estimations, we utilize a “rating/PD buckets bootstrapping” methodology. WebOct 6, 2015 · 2 Answers Sorted by: 2 One approach would be to model this as an integer program. Let's assume there are "m" numbers y_1, y_2, ..., y_m and "n" buckets. Define variables x_ij, with an index "i" for each of the numbers you are trying to assign and an index "j" for each bucket.
