[R] General question on prediction

[gwiggner@lix.polytechnique.fr]

Hi,

Could you give me your opinions on this idea, please ?
Predicting Y from X is similar* to finding the Expectation{Y|X}.
The joint probability Pr(X,Y) 'contains' this expectation.
If this joint probability follows a 'simple' law, it is easier to 
estimate it directly than using regression techniques.

Thanks,
Claus
