Cant seem to find information on this anywhere...
If I want to average two values with errors, say
x1 = 10 +/- 2
x2 = 12 +/- 4
I would do a regular weighted average that would reflect the fact that x1 is a more precise measurement.
But what if my errors are asymmetric? So if I had
x1 = 10 +2/-1
x2 = 12 +3/-4
How would I take the average of those values? My first thought was to somehow "normalize" x1 and x2 such that they have symmetric errors, but I am not sure whether that is valid or how I would do that. Anyone have any ideas? thanks...
