In my study I will look for the relationship between the Gini coefficient and trade, FDI and other variables. However, as I was regressing it... the result turn out to be insignificant. My data that I used then were 'trade as a percentage to GDP' and 'FDI as a percentage to GDP'.
On the other hand, when I regress it with just the total of trade and FDI... it brings a somewhat significant result.
Can I drop the 'as a perentage of GDP'? And just use the total trade and FDI without that?
Plus I only have 16 years worth of data, though.
