R11. Shading Under a Bell Curve (Econometrics in R)
In this video, I demonstrate how to shade under a normal density using R. After demonstrating how to shade under a normal density, I give an example of how to plot the Type I and Type II error probabilities using R. The typical method is to use the polygon() command, but I have written a function called shadenorm() that makes shading under a normal density easier. I have made the code for this function available here: https://docs.google.com/document/pub?id=1oZV3vDYqd19Zf2w7PhVrsfaqaRu-aquMBglPKCNa9Yc You can see other functions I have written and other video tutorials at my econometrics blog: http://novicemetrics.blogspot.com This video and the code in the video are posted here: http://novicemetrics.blogspot.com/2011/04/how-to-shade-under-normal-density-in-r.html
