Note(s): The dependent variable is the log of number of backers. P-values are in parentheses, with “***”, “**” and “*” representing the 1%, 5% and 10% level of statistical significance. The variance inflation factors (VIFs) associated with each model specification all fall well below the acceptable threshold of 10, indicating multicollinearity is not a concern. Particularly, for all models VIF is always around 1 which guarantees well-specified models. The check for normality of the standardized regression residuals is satisfied for all models, using tests for normality and q-q plots
