FORECAST OF REVENUE FREIGHT CARRIED BY RAIL IN TEXAS TO 1990

Revenue tons of freight carried by rail in Texas have been forecast to 1990 using multiple regression analysis and trend analysis. Data were gathered on the dependent variable (revenue tons of freight carried by rail in Texas) and on twenty-nine independent variables (economic indicators of the Texas economy) for the base period 1950 to 1972. Forecasts for each of the ten selected variables were computed for 1975, 1980, 1985, and 1990 by extrapolating a chosen trend curve. These forecasted values were then substituted into the regression equation to yield forecasts for the tons of revenue freight carried by rail in Texas.
