Type in the following to get a Q-Q plot and a histogram on top of each other

> hist(dlGDP,prob=T,12)
> lines(density(dlGDP))
> qqnorm(dlGDP)

and the bottom says that they are normal. Ficcissimo!

We can take a look at the correlations between the lags with the following code:


Holy crap- there is strong correlation! This will help give us an idea as to what model we end up choosing.

My guide for this has been the following website:
