Subject: RandomFields: Randomness in realisations of sequential simulation?
Dear all,
I've some general question regarding the implementation of
randomness in RandomFields and sequential simulation.
(1) Is there a difference between running
krige(nsim = 5, ....)
and running
krige(nsim = 1, ....)
for 5 times?
(2) Does repeating of the simulation with the same random number seed
(how to keep the seed?) lead to the same realisations? And: how
random is the path?
(3) Can I fix the parameters (which ones?) to reproduce the same
realisations a later time?
Another question is: How can I generate an 'e-type' of, let's say 10,
realisations, and do some post-simulation analysis like defining
probability to be above or below a certain threshold?
Many thanks in advance!
best,
Andre
