Seems to me that you could just reformulate an EM algorithm to work
directly on the actual (magnitude) responses of the biquad stages, and so
bypass the step of converting from a Gaussian response to the actual biquad
response (along with its attendant error). The only obvious wrinkle that

What's "they" in the comparison, I mean are we talking Frequency Domain
here, where a band filters characteristic pass band curve is to be
replaced by a statistics integral ? Doesn't make much sense

Small values should not be simply omitted. It's sort of an effect size
consideration. Not all variables
Negative coefficients are like a negative correlation. I say "like",
because PCA gives you vectors of associated variables along which the
variance in the data is decomposed. That's not exactly the same as
correlation. The other part to pay attention is the eigenvalues. The
largest components (

There is no simple method that I've ever heard of, but I think this problem
is a good candidate to be solved as an optimization problem. I actually
wrote some MATLAB scripts some time ago to design a filterbank based on a

Thanks so far for the different proposals.
I must admit that I do not have much skills with Matlab.
And it seems the proposals require all steep learning curve.
