Linearly interpolate values
Check this option to add values for all missing time points. This option creates a value for every subject at every time point, so subjects do not disappear at the beginning or at the end of the time range.
How are missing values interpolated?
For any subject in the trial:
|
Missing values for time points occurring... |
Are... |
|
before the time point at which the first observed value was taken |
set equal to the first observed value |
|
in between two observed points |
linearly interpolated between the two flanking observations |
|
after the time point at which the last observed value was taken |
set equal to the last observed value |
