| R2 = Coefficient of determination. |
| D.W. statistic = Durbin-Watson statistic. For an explanation of the Durbin-Watson statistic, see J. Johnston and J. Dinardo, Econometric Methods, New York: McGraw-Hill, 1996. |
| Where: |
| AGE(age) = Age-specific intercept term. |
| Rho(age) = Autocorrelation coefficient for each age. |
| LNRUF = Log unemployment rate for women. |
| LNRYPDRNMA = Log of three-period weighted average of per capita disposable income in 2000 dollars, using the present period and the previous two periods. |
| NOTE: The regression method used to estimate the full-time and part-time equations was the pooled seemingly unrelated regression method with a first-order autocorrelation correction. The time period used to estimate the equations is from 1975 to 2006. The number of observations is 374. For additional information, see M. D. Intriligator, Econometric Models, Techniques, & Applications, New Jersey: Prentice-Hall, Inc., 1978, pp. 165–173. |
