cmod_man
manually creates a covariance model
object (cmodMan
) for geostatistical data.
1 | cmod_man(v, evar = 0)
|
v |
The covariance matrix of the observed data, including any errors. The matrix should be square, symmetric, and positive definite, though that latter two conditions are not checked. |
evar |
The variance of the errors. Must be non-negative number. The default is 0. |
Note that v
includes the error variance, i.e.,
v = vz + ve
, where vz
is the covariance
matrix of the filtered process and the variance matrix
of the errors is ve = diag(evar/weights)
, where
the weights
come from the geolm
object the
cmodMan
object is associated with.
Returns a cmodMan
object.
