Hello--
I am trying to figure out how to calculate the correlation of first differences for two variables, poverty and violence rates, for the years 1993 to 2004. I assume that I need to identify my dataset as a time series, so I entered the tsset command and identified the time variable as years, 1993 to 2004. However, I do not know what command or formula to use to generate the first difference for these rates. Can anyone offer some guidance? Thanks
