OAI.JointDickman.reciprocalShortAverage_eq_logarithmicline 43Source documentation
Before normalization, the reciprocal short average is the exact logarithmic-window sum, with no endpoint error.

OAI.JointDickman.norm_shortAverage_le_logarithmicline 57Source documentation
A hard short average is bounded by its normalized logarithmic window plus the uniform endpoint-scale error.
