Problems with funnel plot asymmetry p values?
I am hoping someone here can help me. I have generated the below funnel plot using JASP and checked the 'rank test for funnel plot asymmetry' box to estimate a p value for asymmetry. However, as you can see, the p value is 1.000 - which does not look correct when compared to the visual asymmetry in the funnel plot?
Is anyone else having this issue? Any help would be appreciated! Thank you
