Hi

If I want to fit some data using:

output = FindFit[data,
      Izero*(1 + 1/(xiPEG^2*q^2)), {{Izero, 0.12}, {xiPEG, 10}}, q]

I can assign a starting value to my parameters (like 0.12 for Izero in 
the above case), but can I also restrict its value to a certain range 
(like 0.10<Izero<0.14)?

Thanks for any hints!
regards
Laurent
