Predictive ratios for age and sex groups under three models in 2000

Model’s predictive ratio* (N = 10 000)
age and sex with
Sex and age groups age and sex two-diagnoses seven-diagnoses
men aged 0-64 1.06 1.03 1.01
men aged ≥65 0.76 0.89 0.95
women aged 0-64 1.02 1.00 1.00
women aged ≥65 0.86 0.99 1.03

*The mean predicted expenditures are divided by the mean actual expenditures; ratio = 1.0 indicates accurate prediction, ratio <1.0 under-prediction, and ratio >1.0 over-prediction;

†The model includes age, sex, and dummies, presence of hypertension and diabetes.

‡The model includes age, sex and dummies, presence of hypertension, diabetes, obstructive bronchitis syndrome, chronic bronchitis, asthma, alcohol abuse, and ulcer with varices.
