Methods, systems, and apparatus, including computer programs encoded on computer storage media, for receiving a source code change; computing a distribution of standard coding durations using a model that takes as input features of source code changes; and computing a representative duration for the code change using the distribution of standard coding durations, wherein the representative duration represents a measure of how long a standard developer defined by the model would take to make the code change.

Coding output

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for obtaining a commit time history of a developer entity, wherein the commit time history indicates, for each unit time interval of a plurality of unit time intervals, whether or not the developer entity committed source code during the unit time interval; and generating a model that takes the commit history as input and generates an output sequence of final probabilities, each final probability representing how likely it was that the developer entity was active during the corresponding unit time interval.
