The data is collected from all public repositories operated by CIRCL where the content was produced by CIRCL team members

The tool Sloc Cloc and Code (scc) is used to perform the COCOMO calculation.

Then, it applies the COCOMO model using the "Organic" development mode.
Additional parameters are also applied to increase the accuracy:
