Repository with an example of PLS-PM structural equation modeling with stratified bootstrapping

Models for the paper:

'Environmental changes produce different responses on ecosystem water use efficiency in an old-growth temperate rainforest and an anthropogenic peatland'

yet to be submitted

Models include the prediction of Gross Primary Production (GPP), Evapotranspiration (ET), Water Use Efficiency (WUE), Inherent Water use Efficiency (IWUE), and Intrinsic Water use Efficiency (iWUE) for a Template Rain Forest (TRF) and a Peatland (AP) of Chilean Patagonia.

The climatic drivers included as predictors are: solar radiation (Rg), air temperature (Ta), vapor pressure deficit (VPD), wind speed (U), precipitation (P), soil water content (SWC), water table depth (WTD), and surface conductance (GS).

All data was obtained from Eddy Flux towers with monthly intervals between 2014 and 2017.

Model structures are the following:

where model 1 correspond to GPP, ET, and iWUE, model 2 correspond to WUE, and model 3 correspond to IWUE.
