It is not the sample (height) variance, it is already the estimated error of the mean (or actually, error derived from the estimated errors of mean heights of the individual line segments using the law or error propagation).

The standard ones, there is no fancy statistics there. Actually, not even Student coefficients and used and the way things are implemented the denominator in the error estimate for the mean contains n instead of (n-1). So reasonably long segments are assumed, otherwise the uncertainties are underestimated.

Hi,
I'm interested in the type of error which is displayed when fitting a graph. Especially using 'Edge height (left|right)'.
Is it simply the variance or anything else?

Thanks for the really fast reply.
Can you tell me what kind of
- estimation of the error of mean heights of the individual segments
- law of error propagation
ist used?

Great, that's all I need.
You helped me a lot.
Thanks again for your fast reply.
