Can anyone help me? Here's what I want to do: I have two sets of data which are related in such a way that, when plotted, they should have the same shape (or I want to force the curve fits to have the same shape), but at a different location. So, for example (and simplicity} suppose I have two sets of data which can be fit by lines, y=mx+b. I want to fit data set 1 to (y-y1)=m(x-x1)+b, and data set 2 to (y-y2)=m(x-x2)+b, where m and b are common and xn and yn are specific to the data set. This is a fairly easy to do indirectly, even by hand, but is there a way to get Mathematica to do this directly, i.e., finding the two curve fits concurrently? Obviously, I'm trying to do this for much more complex models. Any input would be appreciated. Thanks, -rdc.
