Choosing a Method
How to Choose an Analysis Method Dependent on Purpose
HEI scoring and analysis methods vary by the primary purpose of the analysis: monitoring dietary intakes for a population using HEI score, examining relationships between HEI scores and other variables, and evaluating interventions using HEI scores.
Figure 1. This figure illustrates some possible research goals and analytic methods to consider. For some research goals, the SAS code remains under development for the recommended analytic method. Thus, available analytic methods for which SAS code have been developed are listed; though researchers should note these methods have limitations.
*Multivariate Markov Chain Monte Carlo (MCMC) method for relating HEI components/score to an outcome is currently under development."
