High P Values

[darmanin]

I am in the process of carrying out OLS for the following data.

GFCF is not normally distributed so the LOG was calculated.
ADF and PP were carried out on all variables GDP, FDI, LOGGFCF and Tertiary resulted as being non-stationary so these were differentiated in order to become stationary.

OLS Regression was then carried out on the following data



Below are the results of my OLS regression. As you can see Prob values are quite high and I believe something is wrong.

You only have 13 observations. Probably nothing is wrong.
