### R13. Statistical Power (Econometrics in R)

In this video, I demonstrate how to compute and graph statistical power as a function of the assumed-true alternative hypothesis. Along the way, I show an example of how to write a function in R. This video is a part of my "Econometrics in R" series of videos, where I post video tutorials on common/ useful R calculations for econometrics. I have also been posting supplemental material (code, data and comments on motivation) to my econometrics blog: http://novicemetrics.blogspot.com The code I use in this video is available at this post: http://novicemetrics.blogspot.com/2011/04/computing-statistical-power.html
