ot_cdist module¶
Composed distribution based on OpenTURNS¶
Overview¶
The OTComposedDistribution
class is a concrete class
inheriting from ComposedDistribution
which is an abstract one.
OT stands for OpenTURNS
which is the library it relies on.
Construction¶
The OTComposedDistribution
of a list of given uncertain variables
is built from a list of OTDistribution
objects
implementing the probability distributions of these variables
based on the OpenTURNS library and from a copula name.
Note
A copula is a mathematical function used to define the dependence between random variables from their cumulative density functions. See more.

Constructor.
 Parameters
distributions (list(OTDistribution)) – list of OT distributions.
copula (str) – copula name.

COPULA

cdf
(vector)[source]¶ Evaluate the cumulative density functions of the marginals of a random variable for a given instance.
 Parameters
vector (array) – instance of the random variable.
