## Example 2014.7: Simulate logistic regression with an interaction

June 24, 2014
By

Reader Annisa Mike asked in a comment on an early post about power calculation for logistic regression with an interaction. This is a topic that has come up with increasing frequency in grant proposals and article submissions. We'll begin by showing how to simulate data with the interaction, and in our next post...

## Stacking Regressions: Latex Tables with R and stargazer

May 3, 2014
By

In my paper on the impact of the shale oil and gas boom in the US, I run various instrumental variables specifications. For these, it is nice to stack the regression results one on the other – in particular, to have one row for the IV results, one row for the Reduced Form and maybe

## Example of linear regression and regularization in R

April 28, 2014
By

When getting started in machine learning, it's often helpful to see a worked example of a real-world problem from start to finish. But it can be hard to find an example with the "right" level of complexity for a novice. Here's what I look for: uses r...

## Use of freqparcoord for Regression Diagnostics

April 14, 2014
By

This is the third in my series of three posts on my package freqparcoord with Yingkang Xie. (My next post after this will show how to use R to explore one of my favorite examples of “what can go wrong” in statistics.) Here is a very brief review of my previous posts regarding freqparcoord. A

## Regressions with Multiple Fixed Effects – Comparing Stata and R

April 5, 2014
By

In my paper on the impact of the recent fracking boom on local economic outcomes, I am estimating models with multiple fixed effects. These fixed effects are useful, because they take out, e.g. industry specific heterogeneity at the county level - or state specific time shocks. The models can take the form:    where is

## Regression with multiple predictors

February 18, 2014
By

(This article was first published on Digithead's Lab Notebook, and kindly contributed to R-bloggers) Now that I'm ridiculously behind in the Stanford Online Statistical Learning class, I thought it would be fun to try to reproduce the figure on page 36 of the slides from chapter 3 or page 81 of the book. The result is a curvaceous surface...

## Solutions for Multicollinearity in Regression(2)

February 16, 2014
By

Continue to discuss this topic about multicollinearity in regression. Firstly, it is necessary introduce how to calculate the VIF and condition number via software such as R. Of course it is really easy for us. The vif() in car and kappa() can be applied to calculate the VIF and condition number, respectively. Consider the data from … Continue reading...
