Issue:
How are the error bars calculated for a regression model and can they be related to a confidence limit (confidence in the prediction)?
Possible Solutions:
The error bars reported for inverse least squares models (and from the Ils_esterror function) represent the estimation error for each prediction, see:
Faber, N.M. and Bro, R., Chemomem. and Intell. Syst., 61, 133-149 (2002)
They can be read as a standard deviation of the estimate. However because the underlying distribution is not clearly known (and is a matter of research), a confidence limit is not reported.
