I don't have any insights on specific models that are "out there", but I'll share one tidbit you might find of interest if you're not already familiar with it. Douglas Hubbard's "Applied Information Economics"[1] is a methodology that could probably be applied to doing what you're asking for. Is it the only such methodology? Almost certainly not. Is it the best? I really don't know, as I think the scope of what you're looking at goes a little beyond what Doug originally intended for AIE. But it could potentially still be applied there, I think.
Thanks. From the linked page I only see a marketing page that sells the general ideas. It looks like the common pattern where a consultancy sells their expertise, perhaps with a differentiating advantage that their analysis is backed by a quantitative model that has been refined over time. I don’t know how they work, but they probably custom build or tailor their in-house model and provide the results and interpretation to clients.
Maybe they even allow clients to play around with the model directly, but I wouldn’t bet on it. I’m guessing they gate access to it via consulting fees. One wouldn’t want a client to “misinterpret” the model, would we? :P
Furthermore, the idea of open sourcing their base model isn’t probably something that they would consider; it is likely perceived as incompatible with their business model.
There's no "model" there, just a methodology. Hubbard does consulting and sells books, that's how he monetizes this as far as I know. His book How to Measure Anything[1] lays out the core ideas in sufficient detail for somebody to implement the basic idea. A used copy could be acquired for < $10 if one were interested in learning more.
