Statistical Modelling Songs

La mejor fusión entre el jazz y la estadística nos la ofrece en sus canciones estadísticas Michael Greenacre, catedrático de Estadística en la Universidad Pompeu Fabra en Barcelona y compositor.

Y para muestra aquí tenéis una canción con la adaptación estadística de la letra realizada por el propio Greenacre:

It ain’t necessarily so

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!
