What sense does it make to fit using a smaller interval than x[0] ...  
x[-1]? You'd then be throwing away some of your observations. An xb  
and xe value < or > might do something

I don't see why you're specifying xb and xe to begin with. If you're  
fitting it to all the data, simply omitting those arguments makes most  
sense. You can slice your input arrays if you'd prefer not to use all  
of your data.
