Hi Mik,


I think such result could happen when there is diversity in preference (e.g., positive and negative). Further exploration should be of interest, right?


Cheers,

Fan

Fan,

Note that for lognormally distributed parameters the estimates for the
underlying normal are typically reported. So, even though the mean of
the normal is = 0 the mean of lognormal would be positive and could be
significant.

Cheers,
Mik
