Hi Guys,
I have recently ran an acbc study where my none-utility is very very low, which is raising red flags for me.
Pretty much every simulation I run has 100% of my products being chosen.
Even when I run the calibrated none set to a purchase intent of 5/5 my none barely increases - if at all.
Any price which is mildly below average has the ability to make a product selected over and above none.
It appears that this only occurs when I use the zero-centered diffs and not the raw utilities.
So two questions -
1) is this something that sounds familiar? That has a particular fix?
2) can I just manually increase the level of the none-utility to a level where current retention is reached and then just test my products from there?
Thanks for any help,
Dean
