post hoc statistical power
...power, its
meaningfulness, advantages and disadvantages. I thought the issue was
settled after Tukey's 1993 paper about post hoc statistical power
being "essentially meaningless once the experiment has been done".

Literature analysis
Dear all,

references and year.
This could be done by "refviz" a software, which is only running on
