This tool computes a linear fit when there are uncertainties in x data and y data. The best slope and intercept are computed by minimizing the chi2 calculated using both standard deviation on x and y (Deming fit). Data points are simulated using a Monte Carlo method so as to obtain the error on the fitted parameters.
If error on both x and y is not specified, error is assumed constant on y and computed.
Result of the fit is by default displayed, the best fit and a hull of all the possible fits are drawn.

Just one question: which is the level of the confidence lines plotted in the figure? 95%? or 90%?
One small thingy: when you do not plot, a figure still appears. I changed that by putting the holdstatus (line 100) to:
and it works.
Correction of an old bug. Now if 'plotting' is set to false, the correct comportement is obtained: no plot is displayed.
