I harvested GDP data (in current prices, constant price and rates) over 70 years (I have downloaded it), by region (and geographic subset - this is not important).
However, in my table, each year becomes a variable. From there, when I pass it in statistical software, we cannot do time series studies. We cannot even do graphs.
The software thinks 1970 = variable. No, 1970 is a n in "time", with time going from 1939 to 2012.
Does someone know what i could do in order to do so that i have a variable "time" ?
Someone told me that i need something like that: GDP2000, GDP2001, GDP....20xx.
I don't need to make very sophisticated analysis here, it's more about comparing (but comparing in details).
thanks a lot !
