The Durbin-Watson Statistic, D, Is Defined As $d = \sum _ { i = 2 } ^ { n } \left( e _ { i } - e _ { i - 1 } \right) ^ { 2 } / \sum _ { i = 1 } ^ { n } e _ { i }$

True/False

The Durbin-Watson statistic, d, is defined as $d = \sum _ { i = 2 } ^ { n } \left( e _ { i } - e _ { i - 1 } \right) ^ { 2 } / \sum _ { i = 1 } ^ { n } e _ { i }$ , where e_i is the residual at time period i.
