What's meant by 'affine' model in physical sciences? I guess it's related to some ideal or benchmark model?
affine transform has nothing to do with affine model?A ideal model is compared with a real example.
The connection or mapping between the two is an 'affine transform'.
An affine transform preserves parallel lines.
I guess the model of the ideal could be called an 'affine model'.
There seems to be no such thing as an "affine model".affine transform has nothing to do with affine model?
