The LoDI Index uses linear regression analysis to combine cargo volume data from rail, barge, air, and truck transit, along with various economic factors. The resulting indicator is designed to predict upcoming changes in the level of logistics and distribution activity in the US and is represented by a value between 1 and 100. An index at or above 50 represents a healthy level of activity in the industry
