An introduction to function-on-scalar regression
- Abstract
Function-on-scalar regression models feature a function over some do- main as the response while the regressors are scalars. Collections of time series as well as 2D or 3D images can be considered a functional response. We give a hands-on introduction into a flexible semiparametric approach for function-on-scalar regression, using spatially referenced time series of ground velocity measurements from large-scale simulated earthquake data as a running example. We discuss important practical con- siderations and challenges in the modelling process and outline best practices. The outline of our approach is complemented by comprehensive R code, freely available in the online appendix. This text is aimed at analysts with a basic understanding of generalized regression and spline-based estimation.
