Helping people understand the economy, housing and mortgage markets


  1. Comparing recent periods of mortgage rate increases

    In this post we compare recent periods of mortgage rate increases. We'll remix a chart and try out some alternatives to visualize periods of rising rates.

  2. Plotting U.S. Macroeconomic Trends with FRED and R

    Let's plot recent U.S. macroeconomic trends with R.

  3. Housing construction and employment trends

    The U.S. isn't building enough homes to meet demand. One reason often cited is a lack of labor. How do construction trends compare to construction employment? Let's take a look.

  4. Majestic mortgage rate plot

    COME AND MAKE A MAJESTIC MORTGAGE RATE PLOT WITH ME. We'll use R to make a fun plot showing just how low mortgage rates in the U.S. are relative to historical averages.

  5. Tour of U.S. metro area house price trends

    Let's take a tour of recent house price trends in the United States. We will build an awesome visualization with R and then export it to PowerPoint. From PowerPoint we will make a sweet video.

  6. JOLTS a dataviz trilogy

    A trilogy of animated data visualizations showing labor market trends. R code for the data wrangling and plotting bits.

  7. A note on competing risks

    A small note on a statistical result. Some simulations and maximum likelihood estimation with R, Broom and Purrr.

  8. A closer look at forecasting recessions with dynamic model averaging

    Back we go into the vasty deep. In this post we look closer at using dynamic model averaging and dynamic logistic regression to forecast recessions.

  9. Forecasting recessions with dynamic model averaging

    We go into the vasty deep, dipping our toes ever so slightly into the dark waters of macroeconometric forecasting. Here we use dynamic model averaging to forecast recessions with R.

  10. Combining PowerPoint and R's tweenr for smooth animations
