Calculates temporal covariance based on distance matrix
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.
simple.cov.time(T, t.type, t.par)
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. |
Returns a covariance matrix.
