Measuring Bias in Published Work

In a series of previous posts, I’ve spent some time looking at the idea that the review and publication process in political science—and specifically, the requirement that a result must be statistically significant in order to be scientifically notable or publishable—produces a very misleading scientific literature. In short, published studies of some relationship will tend

Programming instrumental music from scratch

I recently posted about automatically making music. The algorithm that I made pulled out interesting sequences of music from existing songs and remixed them. While this worked reasonably well, it also didn’t have full control over the basics of the music; it wasn’t actually specifying which instruments to use, or what notes to play. Maybe I’m being...

Exploratory Data Analysis: Combining Histograms and Density Plots to Examine the Distribution of the Ozone Pollution Data from New York in R

Exploratory Data Analysis: Combining Histograms and Density Plots to Examine the Distribution of the Ozone Pollution Data from New York in R

Introduction This is a follow-up post to my recent introduction of histograms.  Previously, I presented the conceptual foundations of histograms and used a histogram to approximate the distribution of the “Ozone” data from the built-in data set “airquality” in R.  Today, I will examine this distribution in more detail by overlaying the histogram with parametric

shinyPsychometric: simulating how experimental choices affect results uncertainty

In the R community, Shiny is trending a lot. Shiny is an R package for developing interactive web applications. I wanted to give it a try, and ended up with an app to simulate the impact of data collection choices on the outcome reliability of a curve fitting process. I wrote the code behind it

Making infographics using R and Inkscape

I have been making charts with R for almost as long as I have been using R, and with good reason: R is an amazing tool for filtering and visualizing data. With R, and particularly if we use the excellent ggplot2 library, we can go from raw data to compelling visualization in minutes. But what if we want...

Generating Sankey Diagrams from rCharts

A couple of weeks or so ago, I picked up an inlink from an OCLC blog post about Visualizing Network Flows: Library Inter-lending. The post made use of Sankey diagrams to represent borrowing flows, and by implication suggested that the creation of such diagrams is not as easy as it could be… Around the same
