Appendix A Equation - The estimate of the log-odds ratio, lor hat, sub s and a, is defined as the logarithm of the ratio of two quantities. The numerator of the ratio is p 2 sub s and a, divided by 1 minus p 2 sub s and a. The denominator of the ratio is p 1 sub s and a, divided by 1 minus p 1 sub s and a, where p 1 sub s and a are the 2002–2003 State estimates and p 2 sub s and a are the 2003–2004 State estimates.
