Cross-sectional regression model classes based on functional vs. scalar predictor variables (i.e., covariates) and functional vs. scalar outcome variables. We take the FoFR, FoSR and SoFR to be the single level (non-longitudinal) versions of these methods.
| Functional Outcome | Scalar Outcome | |
|---|---|---|
| Functional Predictors | Function-on-Function Regression (FoFR) | Scalar-on-Function Regression (SoFR) |
| Scalar Predictors | Function-on-Scalar Regression (FoSR) | Generalized Linear Models (GLM) |
