(I assume my measurements are accurate, I only want to estimate the aggregation error.) Currently I use the MIN and MAX values of my data as the absolut error of my measurements. But then i am not really sure if that is not grossly overestimating the error - AVG is average for a reason, after all. Did anyone do some thinking about this? How do i do reasonable error estimation, given that all MIN, MAX and AVG are actual, "accurate" values in the given time frame? --001a11471aa860e09b055bbe880d Content-Type: text/html; charset="UTF-8" Content-Transfer-Encoding: quoted-printable <div dir=3D"ltr">Hi,=C2=A0<div><br></div><div>I am in the process to calcul= ate the error introduced by consolidating the data.
