Analogy as an argumentative transfer

I contend that anological argumentations transfer an argument from one domain to another, intending that the target argument will be good if the source argument is good. After analysis of some philosophical arguments traditionally taken to be analogical. I conclude that there are two kinds of analogical transfer. When some abductive principle like similar cases should have similar explanations is used. the target argument is weaker than the source argument; when it is claimed that the same reasons hold in both domains the strength of both arguments is proportional.
