Perquè no em van ensenyar l’estadística d’aquesta manera?

It ain’t necessarily so,
It ain’t necessarily so
That for models to be formal
Errors have to be normal
But it ain’t necessarily so.

My data had values real skew,
Relationships nonlinear too,
But with spline approximation
Or Box-Cox transformation
My data are more normal than you!

Now it ain’t necessarily so
That your deviance has to be low,
Use less parameters,
Less alphas and betas,
Then apply Akaike,
Although it sounds freaky,
And less will be more as you know…
