36 This checking algorithm provides a simple analysis of the characteristics of
37 the state collection from the point of view of reduction. It aims to diagnose
38 the complexity of the information present in the available state collection,
39 and the possibility to represent this state information in a space smaller than
40 the entire state collection. Technically, based on a classical SVD (Singular
41 Value Decomposition) and in the same way as a PCA (Principal Component
42 Analysis), it evaluates how information decreases with the number of singular
43 values, either as values or, from a statistical point of view, as remaining
44 variance.
45
46 Once the analysis is complete, a summary is displayed and, on request, a
47 graphical representation of the same information is produced.

92   *List of names*. This list indicates the names of the supplementary
93   variables, that can be available during or at the end of the algorithm, if
94   they are initially required by the user. Their availability involves,
95   potentially, costly calculations or memory consumptions. The default is then
96   a void list, none of these variables being calculated and stored by default
97   (excepted the unconditional variables). The possible names are in the
98   following list (the detailed description of each named variable is given in
99   the following part of this specific algorithmic documentation, in the
100   sub-section "*Information and variables available at the end of the
101   algorithm*"): [
