Hi, I measured the hall-current of a Ge-semiconductor. The experiment yielded data for the current and for the voltage, both with their own error. Both measurements are uncorrelated. Now both the voltage and the current have individual uncertainties due to the method of measurement. How can I perform a linear fit of this dataset and incorporate both errors? Ralph Kube
