Question about Penalty Analysis

By Raul Villarreal | Dec 11, 2016 07:50AM CET

Hi, i had a question about penalty analysis.
What happens if an attribute (example: saltiness) is red in the mean drop chart and in the penalty analysis is green? How do you interpret that?

Hi,

This can happen in the following situation:
- You have an important size effect for one of the two mean drops, which results in a significant effect for this specific drop.
- The second mean drop has a weak size effect, but important weight (“frequency” column).
When averaged together to compute penalty, the size effect of the strong mean drop is faded away by the important weight of the weak mean drop.

Best,

Jean Paul
