kmNoNugget.init {DiceKriging} | R Documentation |
kmNoNugget.init
is used to give initial values to fit kriging models when there is no nugget effect nor noisy observations.
kmNoNugget.init(model)
model |
an object of class km . |
The procedure can be summarized in 2 stages:
1) | If no initial value is provided by the user for the covariance parameters, simulate them uniformly inside the domain delimited by model@lower and model@upper . The number of simulations is the one given in model@control$pop.size . |
2) | Compute the likelihood for each parameters set, and select the one that gives the highest value. |
