Dear Professor Sudret;
Dear Dr. Marelli;
Dear all developers and contributors,
First and foremost, Thanks for the state of the art framework, UQLAB.
I have some misunderstandings about copula families and types. Here are my assumptions:
- If we want to show dependency between the marginals properly, we can use copula.
- The above mentioned copula can be written:
InputOpts.Copula.Type = ‘Pair’;
InputOpts.Copula.Family = ‘Gumbel’;
InputOpts.Copula.Parameters = 1.5;
- There is another form of dependency definition in section 126.96.36.199 (UserManual_Kriging):
MetaOpts.Corr.Family= ’ matern-5_2 ’
MetaOpts.Corr.Type= ’ ellipsoidal’
- Another Example (188.8.131.52 (UserManual_Reliability)):
AKOpts.AKMCS.PCK.Kriging.Corr.Family = ‘Gaussian’;
Please help me in understanding the differences between
the “.Corr.Type= ’ ellipsoidal”, “.Kriging.Corr.Family = 'Gaussian’” and marginal copulas?
In a sentence, if we want to define a full dependent model using copula along with metamodels such as pck, what is the right approach?
