N |
Sample size. |
base |
Base model, |
lagrangian |
Lagrangian model, "none" or |
par_base |
Parameters for the base model (symmetric). |
par_lagr |
Parameters for the Lagrangian model. |
lambda |
Weight of the Lagrangian term, |
dists |
Distance matrices or arrays. |
sd |
Standard deviation for each location. |
lag |
Time lag. |
scale_time |
Scale of time unit, default is 1. |
horizon |
Forecast horizon, default is 1. |
init |
Initial samples, default is 0. |
mu_c , mu_p |
Means of current and past. |
return_all |
Logical; if TRUE the joint covariance matrix, arrays of distances and time lag are returned. |
Simulated Markov chain Gaussian field with user-specified covariance
structure. The simulation is done by kriging. The output data is in
space-wide format. dists
must contain h
for symmetric models, and h1
and h2
for general stationary models. horizon
controls forecasting
horizon. sd
, mu_c
, mu_p
, and init
must be vectors of appropriate
sizes.
