How do I get the error on fit parameters in Diadem

[schoric]

I am using Diadem "linear least-square fit" with weighted Y-channel. The typical fit model is y=a+b*x. Here is my question:

How do I get the error on the fit parameters a and b ?

Okay, I can ask Diadem to calculate the co-variance matrix, and then use a script to calculate the errors, but there must be a short-cut?

Hi schoric,

The only quantitative regression fit assesment that is built into the DIAdem function is the coefficient of determination of the regression (r^2), which is stored in the global DIAdem variable:

 

RegrPrecision

Does that help?

Hi Brad,
