Analizo::Metrics - reporting project-level and module-level metrics
Analizo reports both project-level metrics, which are calculated for the entire project, and module-level metrics, which are calculated individually for each module. On the project-level, Analizo also provides basic descriptive statistics for each of the module-level metrics: sum, mean, median, mode, standard deviation, variance, skewness and kurtosis of the distribution, minimum, and maximum value.
As a project decision, Analizo consider metrics with 0 (zero) value as the same meaning of "null value", in other words, 0 (zero) has no meaning in the context of Analizo metrics calculation, both to project-level metrics as to module-level metrics. You can see a discussion on the issue #60 about this decision.
