Arguments

x

data.frame or SpatialPointsDataFrame of observations with covariates

model

model formula written as character

fixXI

Power of the Tweedie model (tweedie)

modeltype

sub-model type

x_lcc

Projected version of x for kriging

MaxDist

Maximum distance for variogram ("Krige*" modeltype only)

Phi

Range for Phi fitting ("Krige*" modeltype only)

Model

Model type for variogram ("Krige*" modeltype only)

fix.lambda

logical, indicating whether the Box-Cox transformation parameter lambda should be regarded as fixed (fix.lambda = TRUE) or should be be estimated (fix.lambda = FALSE). Defaults to TRUE.

lambda

value of the Box-Cox transformation parameter lambda. Regarded as a fixed value if fix.lambda = TRUE otherwise as the initial value for the minimisation algorithm. Defaults to 1. Two particular cases are lambda = 1 indicating no transformation and lambda = 0 indicating log-transformation.
