Calculation of key accuracy indexes spanning 1994–2009 evaluating the predictive quality of the D-R and GM(1,1) models.

Note: I-U, I-G, D-U and D-G represent the incidence (I) and deaths (D) of tuberculosis in the US (U) and Germany (G), among HIV-negative TB patients in the. D-R and GM(1,1) define the algorithms from which these values were derived.
