Pls my fellow Nairalanders, especially Economists and Data Analysts, I am carrying out a research work that requires regression analysis. I have gotten data on other variables except Gross Savings and Investment data. All effort to get it from National Bureau of Statistics, CBN Statistical Bulletin and other sources proved abortive. Kindly help your brother.

N/B: I am looking for Gross data on each of the variables (SAVINGS AND INVESTMENT) and not as percentages of GDP.
thanks.
