Receiver operating characteristics curve
James Hamilton (November 18th, 2009) Writes:
Travis Berge and Oscar Jorda of the University of California, Davis have an interesting new paper on statistical criteria for distinguishing economic expansions from recessions.
Berge and Jorda evaluate rules of the form that would declare the economy to be in a recession when some indicator Yt falls below a specified threshold c, for example, saying that the economy is in a recession whenever GDP growth comes in below -0.6%. For any choice of the threshold c, there is some observed fraction of observations for which the economy wasn't in a recession and yet Yt was less than c (the false positive rate), and a fraction of the time when the economy was in a recession and Yt was less than c (the true positive rate). By choosing a lower value for c, there will be fewer false positives and fewer true positives.
