3.1 Statistical Models
Here we describe the 3 types of statistical models we consider:
Parametric Estimation, Kernel Density Estimation, Root Transform Local
Linear Regression. Parametric Models are used in previous work \cite{Guo_2019} \cite{Sheng_2019}. KDE is commonly used in
related studies on renewable energy \cite{Wahbah_2019a}. RTLLR proving more recent method show to
be successful on renewables.
