5Description::
6Principal Components and Karhunen-Loeve are very similar functional forms of the expansion.
7They both use basis functions which are eigenvectors of the covariance matrix of the random field data.
8However, in principal components, we parameterize the coefficients of the expansion to be Gaussian
9process models which are functions of the uncertain parameters used to generate the initial ensemble
10of data representing the random field.
11THIS IS AN EXPERIMENTAL CAPABILITY UNDER ACTIVE DEVELOPMENT.

13<b> Default Behavior </b>
14The default expansion form is Karhunen-Loeve.
