In Part I, we showed how to plot a time series of the change in American beards over time, using a dataset from Robert Hyndman's time series data library. Today, we're going to look at whether the dramatic changes in American male beardfulness seem related to the economy. Did Americans grow recession beards in response to the Panic of 1873? Out of work, did they forgo their frequent trips to the barber (since Gillette didn't invent the personal safety razor until 1904 so they could do it themselves)? Did they go on their job interviews with a face full of mutton chops and just never get called back (by telegram)?
