Eh, there is some interesting information here. The presentation could do with work though.

The formulae should probably contain more detailed explanations (specifically the logarithms as not everyone is going know what $$ln x$$ represents.

Right now, I don't think this should be a mainspace article, but perhaps we could move it into the user's subpage? I'll wait and see what others think before I commit to any changes.
