Regression

Predict, classify, and explain with functional predictors and responses.

The Regression module covers the full spectrum of supervised learning with functional data -- from classical scalar-on-function models to elastic regression, classification, conformal prediction, and model explainability.

  • :material-chart-line:{ .lg .middle } Scalar-on-Function


    Predict a scalar response from functional predictors using FPC regression, PLS, nonparametric kernel methods, and automatic model selection.

    :octicons-arrow-right-24: Scalar-on-Function

  • :material-chart-bell-curve:{ .lg .middle } Function-on-Scalar


    Model a functional response as a function of scalar predictors via FOSR and functional ANOVA.

    :octicons-arrow-right-24: Function-on-Scalar

  • :material-label:{ .lg .middle } Classification


    Classify functional observations using LDA, QDA, k-NN, kernel methods, functional logistic regression, and cross-validated model comparison.

    :octicons-arrow-right-24: Classification

  • :material-swap-horizontal:{ .lg .middle } Elastic Regression


    Phase-invariant scalar-on-function regression and logistic regression under the elastic metric. Jointly aligns curves and estimates the regression model.

    :octicons-arrow-right-24: Elastic Regression

  • :material-lightbulb-on:{ .lg .middle } Explainability


    Interpret functional regression models via permutation importance, partial dependence plots, SHAP values, beta decomposition, and significant region detection.

    :octicons-arrow-right-24: Explainability

  • :material-shield-check:{ .lg .middle } Conformal Prediction


    Distribution-free prediction intervals and prediction sets with finite-sample coverage guarantees for functional regression and classification.

    :octicons-arrow-right-24: Conformal Prediction

  • :material-shield:{ .lg .middle } Robust Regression


    L1 and Huber M-estimation for functional linear models that resist outlier contamination.
