| R2 = Coefficient of determination. |
| D.W.statistic = Durbin-Watson statistic, a test for autocorrelation among regression residuals. For more details see Johnson, J., and Dinardo, J. (1996). Econometric Methods. New York: McGraw-Hill. |
| NOTE: The regression method used to estimate the full-time equation was the pooled seemingly unrelated regression method with a first-order autocorrelation correction. The regression method used to estimate the part-time equation was the pooled seemingly unrelated regression method. The time period used to estimate the full-time equation is from 1973 to 2007 and the number of observations is 385. The time period used to estimate the part-time equation is from 1975 to 2007 and the number of observations is 363. For additional information, see Intriligator, M.D. (1978). Econometric Models, Techniques, & Applications. New Jersey: Prentice-Hall, Inc., pp. 165–173. |
