Public Attributes
DataObjectPtr	bounds_lower
	lower bounds (may be an empty pointer)

DataObjectPtr	bounds_upper
	upper bounds (may be an empty pointer)

MultivariateDistributionTypes::enum_type	distribution_type
	The ident of the probability distribution that is assumed to convert data from original space to Gaussian. If empty (default), then it is automatically chosen.

DataObjectPtr	mean
	mean value of the field

bool	overwrite_existing
	Is true if already existing output data objects will be replaced. In this case, also all depending objects of the already existing one will be deleted.

string	quantity_ident
	the ident of the quantity for which the random field is to be generated

DataObjectPtr	stddev
	standard deviation of the field

Detailed Description

template<dataobject_types TYPE>
class PiecewiseConstantModel< TYPE >

Provides random field models.

Template Parameters

TYPE	the field data type

This class provides a field parameterization similar to random field correlation models. The basic idea is that one creates "tents" around given support points. The tent is actually given through an autocorrelation function (governed by a correlation length parameter) centered around each support point. The supports are defined through sets.

The correlation models employed here refer to the correlation matrix that is created after transforming the field marginal CDF to standard normal space.
