*A pedestrian guide to a new analytical tool*

- A dataset can be checked for consistency with a proposed model
- An empirical model may be determined on the basis of the data alone.

## The core of the matter... |

The relationship between any two points in an n-dimensional space can be characterised by ranking the points on each measure. This can be represented as an n-component signed vector whose entries are either "+", "0" or "-". This forms the basis of an analytical technique to investigate all inter-relationships in an arbitrary dataset. Particular structures have a recognisable signature that allows identification of an appropriate parametrisation of the data. This can be in the form of a matrix of constant (or variable) coefficients or as a collection of relational equations. Alternatively the allowed relationships inherent in a proposed numerical model can be routinely verified with respect to the totality of all available relevant data. |
