Keywords: Dimension reduction, Correlation dimension, Singular value decomposition, Load forecasting
We present a new R package for curve linear regression: the clr package.
This package implements a new methodology for linear regression with both curve response and curve regressors, which is described in Cho et al. (2013) and Cho et al. (2015).
The key idea behind this methodology is dimension reduction based on a singular value decomposition in a Hilbert Space, which reduces the curve regression problem to several scalar linear regression problems.
We apply curve linear regression with clr to model and forecast daily electricity loads.
