Examples of AIC in a sentence
Three models containing a predictive term for 2012 HIV prevalence were built, one with all covariates (M1b), one with a subset that maximized AR2, AIC, and BIC (M1a), and one with solely prevalence as a predictor (M1).
One model included all covariates (M2b), a second included only a subset that maximized AR2, AIC, and BIC (M2a), and one included solely the estimated transmissions term as a predictor (M2).
This more simplistic formulation of the model outperformed all other models in adjusted R2, AIC, and BIC measures.
One model contained all covariates (M3b), one contained a subset that maximized AR2, AIC, and BIC (M3a), and a third solely included the estimated transmissions term as a predictor (M3).
Of the nearly 10% of state-level variation in diagnoses unexplained in a prevalence-only model, accounting for transmissions, state-level variability in the proportion of cases who are diagnosed, and a subset of demographic covariates improved the adjusted R2 value to nearly 95%, a nearly 50% increase in predictive ability that correlated with a drop in AIC from 610.56 to 566.70.
