PSM.vslite

Implement the Vaganov-Shashkin Lite tree ring model

Description

The VS-Lite forward model uses monthly temperature and precipitation to model annual tree ring widths. This model maintains memory of previous years via its internal model of soil moistyre. The model is described in the paper:

User Methods

Create

vslite - Creates a new VS-Lite PSM object

label - Apply a label to a VS-Lite object

Estimate
