| Jul 16, 2013 at 1:15 | comment | added | krokodil | I could not make any assumptions on how sensor produced (x,s) values. They might be based on some hidden iterations or perhaps something else. However it is safe to assume that each (x,s) pair returned to me is independent from others and measuring the same true value of 'x'. | |
| Jul 16, 2013 at 0:22 | comment | added | gung - Reinstate Monica | Some questions: The idea here is that the sensor actually took a number of measurements, and calculated & returned their mean & SD, is that right? Do you know if the measurements from iteration to the next are independent? What is it that you want to do with these measurements in the end? You may also find this thread interesting: algebra-for-data-confidence. | |
