Statistics Collection Recommendations – Teradata 14.10, 15.0 and 15.10 - comment by sghanw

One more question.
Is there any way to check if the Extrapolations happened was due to Random/Dynamic Amp Sampling or Optimizer used UDI information. In other words, can we check which of the above two techiniques were used to extrapolate the stats ? 
 
Thank You,
