VAST: Vector Autoregressive Spatio-Temporal Model

VASTR Documentation

Vector Autoregressive Spatio-Temporal Model

Description

Analyze spatial variatoin in multiple variables representing data species, ages, size-classes, etc. This can be used to implement many types of analysis including:

  • species distribution models with residual spatial and spatio-temporal variation, as well as covariates affecting density and catchability

  • joint species distribution models (both static and dynamic)

  • empirical orthogonal function (EOF) analysis,

  • vector autoregressive modelling,

  • spatial factor analysis,

  • standardization and biomass-expansion of spatially unbalanced samples

Features are built to be compatible among model types, e.g., by allowing catchability and density covariates to be included in EOF analysis.

Details

See fit_model for a simple example of high-level wrapper functions for using VAST.
