The functions or variables listed here are used internally, i.e. they are not intended to be called directly by the user.
control.wendland(numint.abstol = getOption("wendland.numint.abstol"), numint.reltol = getOption("wendland.numint.reltol"), numint.qag_key = getOption("wendland.numint.qag_key"), numint.subintervals = getOption("wendland.numint.subintervals"), interp.method = getOption("wendland.interp.method"), interp.num_support = getOption("wendland.interp.num_support"), cov.reparameterize = getOption("wendland.cov.reparameterize"), cov.eps = getOption("wendland.cov.eps"), cov.d_value = getOption("wendland.cov.d_value"), ...) control.askey(cov.reparameterize = getOption("wendland.cov.reparameterize"), cov.eps = getOption("wendland.cov.eps"), cov.d_value = getOption("wendland.cov.d_value"), ...)
numint.abstol (default: 1e-3) |
Absolute tolerance for numerical integration. |
numint.reltol (default: 1e-3) |
Relative tolerance for numerical integration. |
numint.qag_key (default: 0) |
Method to use in QAG integration (Values 1 - 6) |
numint.subintervals (default: 0) |
Number of subintervals to use in QAG/QAGS integration. |
interp.method (default: 'none') |
Method to use for covariance interpolation. Valid methods are 'none', 'linear', 'polynomial', and 'cspline'. |
interp.num_support (default: 0) |
Number of support points to use for covariance interpolation. |
cov.reparameterize (default: TRUE) |
Whether to apply the reparameterization μ=\frac{1+d}{2} + κ + ν, where ν takes the place of μ in input vector \vec{θ}. This allows users to use box constraints in maximum likelihood estimation, as the covariance function is valid for ν \in [0,∞) rather than μ \in [\frac{1+d}{2} + κ,∞). |
cov.eps (default: .Machine$double.eps^0.5) |
The threshold distance ε below which the function will return σ + θ. |
cov.d_value (default: 2) |
Dimensionality of space in which measurements were taken. This only takes effect if |
... |
Other arguments. Unused. |
The functions control.wendland
and control.askey
are helper functions which create a named list containing the relevant default arguments passed via the cov.args
argument of cov.wendland
and cov.askey
respectively. In addition, users can override the default values.
A named list.
