I have a series of observations made against time. Given perfect observations, the trend should be reasonably linear. As I expect there to be measurement errors, I wish to exclude them from further calculations.
The time values are not evenly spaced either.
How would I go about identifying which values fall significantly outside of the norm here?
Below is an extract of the table:
Time (hrs) Observation
21.516 15.071
21.568 11.555
21.614 12.601
21.675 14.194
21.731 11.308
21.787 11.968
21.842 14.383
23.493 3.269
23.537 5.917
23.581 5.982
23.625 5.696
23.669 10.297
23.713 9.599
23.756 4.074
