Linear regression, error on both vaules x and y

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?
