WebThe r-squared coefficient is the percentage of y-variation that the line "explained" by the line compared to how much the average y-explains. You could also think of it as how much closer the line is to any given point when compared to the average value of y. SEy is the total variation in y (sum of squared distances from the mean of y) and ... WebJun 9, 2016 · Contaminated surfaces play an important role in the transmission of pathogens.
