How to do a global fit in Labview 8.2?

[maxbel1985]

Hello,

I need to do a global fit to my data (i. e. fit multiple curves simultaneously while sharing parameters). Is there an easy way to implement that with existing routines in Labview 8.2?

Thanks in advance for help,

Maxim

Can you post a simple example of what you're trying to do?

A nice short discussion about global fitting is on the Origin 8 website:

http://wiki.originlab.com/~originla/howto/index.php?title=Tutorial:Global_Fitting

My understanding is the following:

There is a set of curves. Each of them can be fitted independently (by minimizing chi-squared), and a set of optimal parameters found separately for each curve.

Otherwise, one could set to minimize the sum of chi-squares from the fitting, which means a single set of optimal parameters will be produced for all curves. And this is global fitting.

Please correct if I'm wrong.
