You can expect to find here a small compendium of proofs, mathematical arguments or just me reasoning through things I have read. I’ll try to keep it focused on Psychometrics, but the fact of the matter is that you’ll probably find some stuff from Geometry, Number Theory and all kinds of stuff every now and then.
I don’t think I’m aiming to be as ‘formal’ as I could be. Mostly because my arguments are basically me explaining things to myself… and maybe some other people will find it useful 🙂
Enjoy! And you can always email me if you think I made a mistake or something it not clear!
