Raw Novice - need some advice

[hinchy70]

Hi all,

Please see attached image. For university I have had to create a basic model, I have opted for a multiple regression model to view the effects of oil price on Saudi GDP. I have run tests for multi-collinearity and heteroskedasticity and there does not appear to be either present. I am abit concerned that my model is appearing to indicate that a rise in price will have a negative effect on GDP, this would appear to be counter intuitive to the real world.

Can anyone give me any tips on this, it would be greatly appreciated!

There are some things you should do before running your regression, namely the unit root tests. It is not clear if you have done it or not.
