This question might look easy for you, but I am kind of new to econometrics and I need your advice.
I am writing a paper where I am researching the relationship of Foreign Direct Investment (FDI) on Gross Domestic Product (GDP). To measure the relationship between FDI and GDP I am thinking to use multiple linear regression, where I would get the significant answer.
But it is not enough for a research paper, so I am planning to investigate from a GDP branch perspective. I have found all the data from every field, like manufacturing, agriculture and etc. branches, which combined is GDP and I would like to investigate each of them.
What method would you suggest to use in order to research the relationship between Foreign Direct Investment and a specific branch of Gross Domestic Product?
Thank you in advance,
