I assume you wanna know what values are for and not what values are exactly...

SRG has a script ( probably several ) that will read each pokemons values to determine different things and how such work throughout the game.

So for example you are asking to fill out the egg type, well the script would read what that egg type is and use that with various other things to determine what comes from breeding and such.
