1For an explanation of the Durbin-Watson statistic, see J. Johnston, Econometric Methods, New York: McGraw-Hill, 1972, pages 251-252. 2AR1 indicates an estimation procedure for correcting the problem of first-order autocorrelation. For a general discussion of the problem of autocorrelation, and the method used to forecast in the presence of autocorrelation, see G. Judge, W. Hill, R. Griffiths, H. Lutkepohl, and T. Lee, The Theory and Practice of Econometrics, New York: John Wiley and Sons, 1985, pages 315- 318. |
| Where: |
|
| DPUTCUR4 |
= Change from the previous year in current-fund expenditures per student in full-time-equivalent (FTE) enrollment in public 4-year institutions in constant dollars | | DPUTCUR2 | = Change from the previous year in current-fund expenditures per student in FTE enrollment in public 2-year institutions in constant 1982-84 dollars | | DPRTCUR4 | = Change from the previous year in current-fund expenditures per student in FTE enrollment in private 4-year institutions in constant 1982-84 dollar s | | DPUED4 | = Change from the previous year in educational and general expenditures per student in FTE enrollment in public 4-year institutions in constant 1982-84 dollars | | DPUED2 | = Change from the previous year in educational and general expenditures per student in FTE enrollment in public 2-year institutions in constant 1982-84 dollars | | DPRIED4 |
= Change in educational and general expendItures per student in FTE enrollment in private 4-year institutions in constant 1982-84 dollars | | DSTREV1 | = Change from the previous year in the sum of personal tax and nontax receipts to state and local governments and indirect business taxes and tax accruals, |
| DSTREV1 |
= Change from the previous year in the sum of personal tax and nontax receipts to state and local governments and indirect business taxes and tax accruals, excluding property taxes, to state and local governments, per capita, in constant 1982-84 dollars lagged one year | | DPCI | = Change from the previous year in disposable income per capita in 1992 dollars | | DPUFTE4 | = Change from the previous year in FTE enrollment in public 4-year institutions in thousands of students | | DPUFTE2 | = Change from the previous year in FTE enrollment in public 2-year institutions in thousands of students | | DPRFTE4 | = Change from the previous year in FTE enrollment in private 4-year institutions to the population in thousands of students |
| DUMMY |
= Dummy variable equaling 1 when the inflation rate is greater than 8 percent and 0 otherwise |
| ININCR |
= Rate of change in the inflation rate measured by the Consumer Price Index |
