Soft Threshold Choice

Comparing the Sage code base to the UCLA-based package, we see a difference in the selection of the 'soft threshold' (beta):

Both algorithms try to find the lowest power whose R^2 is above the given threshold (0.90). If no power achieves the threshold then the threshold is decremented repeatedly by 0.05 until a solution is found. Since the Sage version finds a maximum of 0.887, it carries out the decrementing procedure. The UCLA version finds three values just above 0.90, and picks the lowest.

only 33 are grouped together, the remaining ones are unclustered.

The publication says beta was set to 5.5, not 11. The regression statistics for selecting beta are below, where "Cut" is the value of beta and "Adj R^2" is the value which should exceed a chosen threshold. When the threshold is set to the nominal value of 0.90 , beta=11 is the smallest value for which "Adj R^2" exceeds the threshold. The value of 5.5 would be selected if the threshold were set to 0.80.
