This post provides links to a range of resources related to the use andinterpretation of correlations.I wanted to provide a page with links to a number of additional resources thatwould be useful both for those of my students who might be keen to learn...
Bootstrapping standard errors can be a useful technique when obtaining closed form for the standard error formula is difficult or intractable. In this post, I give an example of how to use R to create a bootstrap sampling distribution in the context o...
I recorded a new video tutorial on how to conduct an IV regression. This time I used my new ivregress() command, which has much better syntax than my old one. There are several reasons I needed to do this:Relative to my previous post on IV regression...
Update: I have added some functionality to my ivregress() command. Check out my newer post here.After I posted my last video tutorial on how to use my IV regression function, I received a comment asking why I didn't write the command a different way t...
Update: I have replaced this video tutorial with a video tutorial on a newer, easier to use IV regression command. Check out that command here.In this video, I show how to use my instrumental variables function in R, ivreg(), along with its companion ...
extrapolation and interpolation The most important lesson I learned from this book: regression is reliable for interpolation, but not for extrapolation. Even further, your observations really need to cover the whole gamut of causal variables, inter...
