%description
A framework for specifying spatially, temporally and
spatially-and-temporally varying coefficient models using Generalized
Additive Models with smooths. The smooths are parameterised with location,
time and predictor variables. The framework supports the investigation of
the presence and nature of any space-time dependencies in the data by
evaluating multiple model forms (specifications) using a Generalized
Cross-Validation score. The workflow sequence is to: i) Prepare the data
by lengthening it to have a single location and time variables for each
observation. ii) Evaluate all possible spatial and/or temporal models in
which each predictor is specified in different ways. iii) Evaluate each
model and pick the best one. iv) Create the final model. v) Calculate the
varying coefficient estimates to quantify how the relationships between
the target and predictor variables vary over space, time or space-time.
vi) Create maps, time series plots etc. For more details see: Comber et al
