Degree correlations
Consider a d isassortative network Which of the following statements correctly describes a characteristic of such a network? a) The Pearson correlation coefficient ( r ) is positive ( r > 0 ), and high-degree nodes tend to link preferentially to other high-degree nodes. b) The Friendship Paradox does not apply in disassortative networks because small-degree nodes preferentially connect to other small-degree nodes. c) The network has a "hub-and-spoke" structure d) The Pearson correlation coefficient ( r ) is negative ( r < 0 ) and high-degree nodes tend to link preferentially to small-degree nodes . e) N.D.A. (None of the Above)
