Any summary list for scale family?
Sorry this might be a dumb question. As the title asked, Is there a list of scale family for random variables so that I don't need to prove them one by one?
Just make sure I stated clearly. scale family is: if Y~ some distribution then cY ~ the same distribution as well (e.g. exponential), where c is a constant. Thanks in advance!
