How to calculate errors for fit parameters?

  1. Jan 26, 2014 #1
    I use the least squares method in a small C-programm to fit some data points. But don't know how to get the errors of the calculated parameter.

    You can track how the sum of squares increase if you vary individual parameters (and optimize the other parameters). Alternatively, use existing fit programs, they have that implemented.
