Nadia Hassan points me to this post by Matthew Yglesias, who writes: Here’s a very cool data visualization from HowMuch.net that took me a minute to figure out because it’s a little bit unorthodox. The way it works is that it visualizes the entire world’s economic output as a circle. That circle is then subdivided […] The post Vizzy vizzy vizzy viz appeared first on Statistical Modeling, Causal Inference, and…

For those of you not familiar with ShinyStan, it is a graphical user interface for exploring Stan models (and more generally MCMC output from any software). For context, here’s the post on this blog first introducing ShinyStan (formerly shinyStan) from earlier this year. ShinyStan v2.0.0 released ShinyStan v2.0.0 is now available on CRAN. This is […] The post ShinyStan v2.0.0 appeared first on Statistical Modeling, Causal Inference, and Social Science.

Last week's post about odds ratio plots in SAS made me think about a similar plot that visualizes the parameter estimates for a regression analysis. The so-called regression coefficient plot is a scatter plot of the estimates for each effect in the model, with lines that indicate the width of […] The post Regression coefficient plots in SAS appeared first on The DO Loop.

I recently read an argument by Andrew Wheeler for using a logarithmic axis for plotting odds ratios. I found his argument convincing. Accordingly, this blog post shows how to create an odds ratio plot in SAS where the ratio axis is displayed on a log scale. Thanks to Bob Derr […] The post Odds ratio plots with a logarithmic scale in SAS appeared first on The DO Loop.

A SAS programmer wanted to plot the normal distribution and highlight the area under curve that corresponds to the tails of the distribution. For example, the following plot shows the lower decile shaded in blue and the upper decile shaded in red. An easy way to do this in SAS […] The post Create a density curve with shaded tails appeared first on The DO Loop.

My son is in high school and plans to take the ACT, a standardized test to assess college aptitude and readiness. My wife asked, "What is a good score for the ACT?" I didn't know, but I did a quick internet search and discovered a tabulation of scores for the […] The post Visualizing the distribution of ACT scores appeared first on The DO Loop.

Bob Nau writes: I know you are not particularly fond of Excel, but you might (I hope) be interested in a free Excel add-in for multivariate data analysis and linear regression that I am distributing here: http://regressit.com. I originally developed it for teaching an advanced MBA elective course on regression and time series analysis at […] The post An Excel add-in for regression analysis appeared first on Statistical Modeling, Causal…

Someone pointed me to this article by Isabel Scott and Nicholas Pound: Recent authors have reported a relationship between women’s fertility status, as indexed by menstrual cycle phase, and conservatism in moral, social and political values. We conducted a survey to test for the existence of a relationship between menstrual cycle day and conservatism. 2213 […] The post “Menstrual Cycle Phase Does Not Predict Political Conservatism” appeared first on Statistical…

CDC should know better. P.S. In comments, Zachary David supplies this correctly-scaled version: It would be better to label the lines directly than to use a legend, and the y-axis is off by a factor of 100, but I can hardly complain given that he just whipped this graph up for us. The real point […] The post Hey, what’s up with that x-axis?? appeared first on Statistical Modeling, Causal…
