What is a max-linear model?
A unit Frechet max-linear process is defined by
where are
independent unit Frechet random variables
and are
non-negative deterministic functions such that

Function "condrmaxstab": Performs conditional simulations for max-stable processes
Since the
functions
are deterministics, Wang and Stoev [2011] proposed an efficient
algorithm to generate conditional simulations from a max-linear
model and thus approximate conditional simulations from a
max-stable process.
However this approach has some drawbacks since it is not clear how to find appropriate functions . Therefore the only available model is currently the (discretized) Smith model for which

constant ensuring unit Frechet margins.
