Hi All 

I would like to do "global fitting" in Mathematica. 

usually what we do fitting in mathematica is just using one model and fit with input data, and it will output the best fitting result with minimized chi-square.
     
This time, i want to fit to two models at the same time, 
using the same input data and would like to have the sum of minimized chi-square. 

Does Mathematica have this function? 
please help me ..

thank you so much 

Jeff
