Rearranging this equation the coefficient of determination is obtained: (23) As shown in this equation, the coefficient of determination, R2, is the ratio of the amount of variation explained to the total variation in y around its mean, or equivalently, the one minus the ratio of the amount of variation not explained to the total variation.

We can rectify that by calculating the coefficient of variation as follows: (5) CV(NCFi) = SD(NCFi) ( E(NCFi) where CV(NCFi) represents the coefficient of variation for net cash flow in the ith year, or business risk per dollar of expected net cash flow. We will use this annual statistic as our measure of exposure to business risk.

unexplained variation (the natural error) as they describe the deviations about the regression line. The . coefficient of correlation. r measures the strength of a relationship. r also indicates the direction of a relationship. r is between where r = 1 indicates a perfect positive relationship and r = indicates a perfect negative relationship.

R2, or the coefficient of determination, is defined as the percent of variation in Y about it’s mean that is explained by the linear influence of the variation of X. Mathematically it is described by: R2 = SSD/TSS and will range between 0 and 1. Closer to one is a poorer model, closer to one is a better model.
