What‘s going on with the tiny grey line in this graph?
If my memory serves me correctly, the vertical grey line indicates that the probability of my coefficient being exactly 0 is 11.4%. The credible interval tells me that my coefficient lies between 0 and 0.401 with 95% certainty. However, in this case...shouldn't the vertical bar and the black curve meet in the same spot? As in, the black curve at x=0 should also be at y=0.114, like the grey line indicates?
Thanks for helping me understand! :)
