3.3. Description of a correlation

We will describe in this section how to precise in Uranie the necessary information to take into account the correlations between variables. There are two ways to specify this: setting the correlation coefficient by hand or couple the two considered attributes with a copula. Both methods are described below.

• 3.3.1. Imposing the correlation coefficients
  • 3.3.1.1. Case of singular correlation matrix
• 3.3.2. The copula classes
