Regression Analysis Showing Yahoo is 446 Times Bigger than Google

Below are the results of the regression analysis. Because the ratios of referring links varied so much from URL to URL, the standard deviation is high. However, notice that the coefficients are much higher than the simple average; Yahoo to Google index is likely to be 446 times bigger given that referring links are proportional to the size of each index.

(Sorry that its a little jumbled, but I am leaving for an important trip tomorrow and don't have time to format it.)
