explain what means COCOMO (and fix description/doc)

[mhow2]

@tdegueul , could you provide something that would help to understand this factoid ?

I can't find anything in the documentation

[tdegueul]

COCOMO is a software cost estimation model (cf. COCOMO). We implemented a simplified version of COCOMO that computes the estimated person-year it took to develop the analyzed project. We use the following formula, where a_i = 3.0 and b_i = 1.12; that is, we evaluate all projects as semi-detached projects):

There was a bug in the current implementation of COCOMO that produced non-sensical results (as in your screenshot). I fixed it in 92d1e97.

Hello @tdegueul,

I was checking your commit 92d1e97 by curiosity, and I found funny the fact that the description of the factoid is COCOMO is crazy along with the comment this method will be removed in a later version. Well, I'm afraid to tell you that that method hasn't been removed, in fact it is used in the platform. Here is the proof :P

Thanks for the explanation @tdegueul . As stated by @creat89 that would be useful to update the description and possibly the metric documentation.

@tdegueul , thank you very much for this improvement! Now it makes a lot more sense.

However, since most of our libraries are quiet small, the majority of them are evaluated with 0 years.
By looking into the code, it seems that both the kloc and years variables are defined as int and storing the results of integer divisions. I think it would make sense to have decimal values like 0.8 or 4.2 person-years, so they should be of float type.

Maybe we can also express the result in "person-months" instead of only "person-years".

What do you (all) think?
