In computations, Analytica represents any uncertain quantity as a random sample Array of values indexed by the standard system index Run. Run is defined as a sequence from 1 to the specified Samplesize -- i.e. the number of samples:
You can modify SampleSize, the length of Run in Uncertainty Setup dialog.
The Mid value of most results is deterministic and is not indexed by Run. The Sample result of uncertain quantities will usually be indexed by Run. See Evaluation Modes.
