data
A spatial3DDataFrame
object containing the necessary data.
tangents
A directions3DDataFrame
object containing structural
geology data. Most likely generated with the GetLineDirections()
or GetPlaneDirections()
method.
model
The covariance model. A covarianceModel3D
object.
mean
The global mean. Irrelevant if a trend is used.
trend
The model's trend component. A formula in character format.
beta
The trend coefficients.
likelihood
The model's log-likelihood given the data.
pre_comp
A list
containing pre-computed values to speed up
predictions.
pseudo_inputs
A spatial3DDataFrame
object containing the coordinates
of the pseudo-inputs.
pseudo_tangents
A directions3DDataFrame
object containing the coordinates
of the pseudo-inputs for directional data.
variational
A logical indicating if the model uses the variational approach.
