[SI-LIST] Simple Rational Model Estimation Method Given Transfer Function

Any suggestions appreciated on simple, preferably open-source, tools to develop 
a good (e.g., in a least-squares sense for both real and imaginary components) 
low order rational model (i.e., pole/zero) given magnitude and phase of a 
transfer function vs. frequency?  The phase info is relatively smooth but the 
roll-off and passband do not look like a second or even 3rd order model would 
suffice.

Any ideas appreciated!

Thanks,

Charlie
