R2 = Coefficient of determination. F-Statistic = Obtained statistic for the F value. Where: Dummy(age) = 1 for each age and 0 otherwise. Rho(age) = Autocorrelation coefficient for each age. LNURM = Log unemployment rate. LNCPIMA = Log of four-period weighted average of per capita real disposable income. NOTE: The regression method used to estimate the full-time and part-time equations was pooled least squares with first-order autocorrelation correction. The time period used to estimate the equations is from 1975 to 1997. The number of observations is 253. For additional information, see The Modern Forecaster by Hans Levenbach and James P. Cleary (Van Nostrand Reinhold Company Inc., New York, 1984, pp. 354-373). SOURCE: U.S. Department of Education, National Center for Education Statistics, Higher Education Enrollment Model.
