Both clases implemenet a common interface so I am using an interface to interact with the object. The block of code is a series of steps that interact with functions of theRead more

I read up on how LinearModelFit/NonlinearModelFit has options to display r-squared value, but this doesn’t suit my case as I already haveRead more
