(1) This is the OLS-estimated slope for the relationship describing how the number of nodes with a given number of out-degree edges scales with out-degree. The data (x) were transformed prior to regression according to log₁₀(x+1). The absolute value of the slope is an estimate for the degree distribution power law exponent (alpha).
