2006 - #16 a: GB method ultimate
2007 - #46 a, b: BF weight, BF drawback, GB advantages over BF
2012 - #1 a: GB BF Dev
\(\star\) 2014 - #5: Credibility weight methods from the Clark paper on LDF curve fitting
- Weight to the Dev method is \((1-q_k)\)
TIA 1: Straight calculate
TIA 2: Back out numbers with formulas
Long calculation
\(\star \star\) 2016 - #1:
Use GB with incremental LR projection
Know the GB method extension theorem
This is from Hurlimann equation with optimal credibility (3.1) and you need that additional assumption for the formula to work
Arithmetics
\(\star\) 2012 - #1 b (fig 2.1): Minor arithmetic
\(\star\) 2013 - #4 a: Back out LDFs with BF and GB methods
TIA 3: Long calc for all years reserve with BF and GB
