simple.cov.time {SpatialTools} | R Documentation |
Calculates temporal covariance based on distance matrix
Description
Calculates a temporal covariance using a (Euclidean) distance matrix T
. Not intended to be used directly by user (though it may be helpful to some). It is used in the covets
function. No argument or error checking is provided for this function.
Usage
simple.cov.time(T, t.type, t.par)
Arguments
T |
A distance matrix. |
t.type |
A character vector specifying the temporal covariance type. Only "ar1" is currently implemented. |
t.par |
A vector of length 1 specifying the strength of dependence of the covariance function. |
Value
Returns a covariance matrix.
