.First, as a reply to Bibas's suggestion that I may have manipulated the data, my answer is: No, I did not manipulate any data. Second, the research I did was for my independent project class, and I included all the variables that I could find. At that time, I could not find the Indian GDP, and therefore could not inlcude it. Third, the t-statistics and high R-squared values that I got in my study were not influenced by any manipulation. Those were what I got from my data. A high R-squared value doesn't only mean my variables were able to explain most of the changes, it also means that there may be a multi-collinearity problem among the variables. And I am aware of that problem. I tried to get rid of it, but could not. Also, my research was definitely not complete, because as you have pointed out, and as I myself have confessed, that there are other important variables that I could have included in my research, but I could not include them because of various reasons and time restrictions.
