### Short data segments

Posted:

**Thu Mar 23, 2006 14:55**Dear all,

In some articles on RP's I often read that the method is also suitable for short data segments of non stationary type (cfr Marwan, Saparin and Kurths "Generalisation of Recurrence Plot Analysis for Spatial Data" 2005 Intl Symp on Nonlinear Theory and Its applications Bruges belgium oct 18=25, 2005. ).

This is of course a very attractive statement but what is "short" ? Surely, the data segment should be long enough for the attractor to become deployed in the phase space ? I will try some test on an EEG data segment ofr different length. Or has this already been done ?

Sincerely,

DR. G. Otte
