It Ain't Necessarily So

Sung by Gurdeep Stephens. Lyrics copyright and music performed by Michael Greenacre.
See also their "The Millenium Song" project.
May sing to tune of "It Ain't Necessarily So" (George Gershwin)

It ain't necessarily so
It ain't necessarily so
That for models to be formal
Data 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, (pronounce: paramee-ters)
Less alphas and betas,
Then apply Akaike,
Although it sounds freaky,
And less will be more as you know...

It ain't necessarily so
It ain't necessarily so
That for models to be formal
Data have to be normal
But it ain't necessarily so.
It ain't necessarily - It ain't necessarily
It ain't necessarily - It ain't necessarily
It ain't necessarily - It ain't necessarily
It ain't necessarily SO!
