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
