Notes: V(ΔNI) is the variability of earnings, which is measured by the variance of the residuals from Equations (1) and (4) to capture the smoothness of earnings; V(ΔNI)/V(ΔCF) is the ratio of variability of earnings to the variability of cash flows from operating activities, where the variability of earnings is measured by the variance of the residuals from Equations (1) and (4), and the variability of cash flows is measured by the variance of the residuals from Equations (2) and (5). This ratio is to capture the smoothness of earnings related to the smoothness of cash flows. We report, in parenthesis, the means and standard deviations of the bootstrapped variance of residuals [V(ΔNI)] and the ratio [V(ΔNI)/V(ΔCF)]. The standard deviation of the bootstrap distribution is our estimate of the standard error of the test statistic which approximates to a normal distribution. All variables are measured during the sample period, 2006-2013
