Software Signals

January 7, 2013 | Carlisle Rainey

This blog post by Sean Taylor generated quite a stir. He discussed the signals one sends by using certain software packages and seems to think that R users are more competent. The reactions ranged from amusement to bashing. In defense of hard to learn statistical tools, i.e. #rstats prsm.... [Read more...]

Packages v. Libraries in R

January 2, 2013 | Carlisle Rainey

In the past I've used the terms "R library" and "R package" synonymously (e.g. this blog post and this paper), but a careful reader has called me out. Mark Sharp notes that there are differences between libraries and packages. Chapter one of the R Manual Writing R Extensions gives ... [Read more...]

December 28, 2012 | Carlisle Rainey

Especially when analyzing time series, we often need plots with two vertical axes. Researchers often expect the two series to \"move together,\" but with different locations and scales. To show that the series move together, you should give each series its own scale. One vertical scale should appear on the ...

An Improvement to Coefficient Plots

July 3, 2012 | Carlisle Rainey

I recently posted about coefficient plots, discussing my approach and providing some example R code to create the graphs. I had the good fortune of hearing Amanda Driscoll give a talk recently, and she made a small, but really nice … Continue rea... [Read more...]

Coefficient Plots in R

June 30, 2012 | Carlisle Rainey

One popular trend in presenting results is the "coefficient plot," an alternative to the table of regression coefficients. I am seeing this a little more often in political science research and have received a few requests for code, so I … Contin... [Read more...]

Multiply Imputing an Outcome Variable

October 12, 2011 | Carlisle Rainey

Some scholars suggest that multiply imputing an outcome variable is incorrect. I use intuition and simulation to argue that multiply imputing outcomes can drastically improve estimates, even in the case of non-ignorable missingness. Continue reading &#... [Read more...]

August 22, 2011 | Carlisle Rainey

Earlier, I discussed the nice properties of bow tie plots for visualizing and understanding inferences from simple randomized treatment experimental designs. R code to quickly create these plots is available here. You can use the command source("htt... [Read more...]
