3D [Power / Sample Size]
Hi zizou,
Your wish is my command. 3D-plots for GMR 0.95. Not sure whether they are more informative than yours.
I know only a few sample sizes by heart. One is for GMR 0.95, CV 30%, and target power 80%: 40 (expected power 81.6%). For Denmark with n=40 we get a mere 76.5%. Note the red contour lines at 70% power. As you discovered as well we never reach 80%. Fascinating the behavior at low CVs. If we increase the sample size, power decreases because a significant difference gets more likely. What a mess.
❝ I know, someone can do it better (eg. in 3D like this kind of figure).
