The derived relationship then allows one to infer from observed yield patterns the true proportion of yield variability explained by soil and management.
But they say that their preliminary findings suggest that economists who have previously studied US income inequality have dramatically underestimated the true proportion of the nation's income once earned by the richest 1percentt.
The study might still underestimate the true proportion of null findings, says Anne Scheel, a psychology researcher at Eindhoven University of Technology in the Netherlands, who is also investigating registered reports.

Consequently, the true proportion of type 2 beneficiaries may be much smaller than predicted.
The true proportion of influenza infection is difficult to assess, because influenza testing is not routinely performed and rapid test sensitivity is only 50-70%[41]].
In Switzerland, intentional injuries forfeit coverage by accident insurance, which could in turn impact reporting, leading to an underestimation of the true proportion of intentional injuries (Le Conseil fédéral 2000).
