1 AR(1) indicates that the models was estimated using least squares with the AR(1) process for correcting for first-order autocorrelation. For a general discussion of the problem of autocorrelation, and the method used to forecast when correcting for 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, pp. 315–318.

Where:
CUREXP = Current expenditures of public elementary and secondary schools per pupil in fall enrollment in constant 1982–84 dollars.
SGRANT = Local governments' education revenue from state sources, per capita, in constant 1982–84 dollars.
PCI = Disposable income per capita in constant 2000 chained dollars.
ENRPOP = Ratio of fall enrollment to the population.
NOTE: R2 indicates the coefficient of determination. Numbers in parentheses are t-statistics.
