Hello,
I have two pairs of columns t1 y1 t2 y2, the time periods overlap but the values of t1 and t2 are not equal.
how can I see the deviation dy(t) for this shared period
or how significant is the deviation of y2 from y1.
Cheers,
Tony |

Hi Tony,
You can run interpolation ("Analysis: Math: Interpolate/Extrapolate" menu) for both Y datasets with
same X range and number of points so that the two results have the identical X datasets.
Then you can calculate the difference between one interpolated Y and the other interpolated Y.
(If you want to plot the difference, you can show the X datasets by choosing "Column: Show X Column" menu,
and turning ON the "Clear Sampling Interval" checkbox on the 1st interpolated Y dataset.)
I'm not sure the significance part because you have only 2 observations at each X, though possible to test.
