Linear fit and Linear fit intervals

[gnappo]

I checked the Parametric Curve Fitting.vi example code and I observed that the Linear fit intervals function is plotted just in the case of Least Squares method. I ask if it is correct or not to plot the results of the Linear fit intervals using the Bisquare option (robust) for the fit. If not, what should one do?

Hi gnappo,

the behaviour that you described is correct. To understand and modify it, please see the differences between cases 0 and 1 of the case structure of the right of the screen.

Ciao!

 Thanks for you reply, but my question is about theory, that is if it's correct or not to use Linear fit intervals with a bisquare fitting option.
