This is Dataplot data file ELNINO.DAT El Nino - Southern Oscillation Meteorology Data Source--Jim Elkins, NOAA Southern Oscillation = barametric pressure difference = Tahiti BP - Darwin BP at sea level Importance--Southern oscillation is a predictor of el nino which in turn is thought to be a driver of world-wide weather. (note--repeated southern oscillation values less than -1 typically defines an el nino) Number of observations = 444 Number of variables per line image = 4 Order of variables per line image-- 1. Response variable = southern oscillation index 2. Factor 1 = year + fraction of year 3. Factor 2 = year (38 years: 1955 to 1992) 4. Factor 3 = month (1 to 12) Statistical category--time series analysis To read this file into Dataplot-- SKIP 25 READ ELNINO.DAT Y X YEAR MONTH Southern Osc.
