`TopoS`

computes one version of the criterion `stress`

as i.e.
known from `sammon`

for a given visualization.

1 | ```
TopoS(EV.dist, Cells.dist)
``` |

`EV.dist` |
a symmetric distance matrix consisting of distances in the origin space ( |

`Cells.dist` |
a symmetric distance matrix consisting of distances in the target space ( |

TopoS first performs a homogeneous linear regression where `dx`

is predicted by `dy`

.
Then the residual sum of squares of this regression is computed and divided by the sum of squared `dx`

.
Finally one minus the square root of the latter result defines `S`

.

`TopoS`

returns a numeric between zero and one which is the criterion `S`

of the given visualization.
