WebRecursive binary splitting (continued) We first select the predictor Xj X j and the cutpoint s s such that splitting the predictor space into the regions {X Xj < s} { X X j < s } and {X Xj≥s} { X X j ≥ s } leads to the greatest possible reduction in RSS. Repeat the process looking for the best predictor and best cutpoint to split data ... WebWhen all series are evaluated using the binary splitting technique (see [4, §4.9]), the first d digits of 7 can be computed in essentially optimal time 0(d1+£). This approach has been used for all recent record calculations of 7, including the world record of 29,844,489,545 digits set by A. Yee and R. Chan in 2009 [9],
