What is the difference between vector space and affine space?

WebMoreover, as the linear model is a simple model, its parameter space is small and it is easy to sample good particles; hence the ABC populations with the linear model have higher acceptance rates. Post departure of the linear model, the acceptance rate drops with the parameter space becoming more complex for the remaining PWL models. WebIn mathematics terms the difference between linear and affine is that linear is of or relating to a class of polynomial of the form y = ax + b while affine is of or pertaining to a transformation that maps parallel lines to parallel lines and finite points to finite points.
