Essay about Article Review
Table 1 is from the article and was set up by the authors.
Table 2 below shows the regression analysis at a 1% significance level along with the standard errors.
Table 2 is also from the article and set up by the authors.
Table 2 is an ordinary Least Squares regression table. This is similar to the simple linear regression we studied in class. As in the simple linear regression, the standard errors in table 2 are the standard deviation of the residuals. Since the numbers are pretty small, the deviation from the regression line is minimal. This tells us there is very little difference between categories. Also, the R-squared numbers in the table are very low. This tells us that there is very little correlation between the observations among the groups. The R-squared
