The string prediction models as invariants of time series in the forex market

Pincak, R. - In: Physica A: Statistical Mechanics and its Applications 392 (2013) 24, pp. 6414-6426

In this paper we apply a new approach of string theory to the real financial market. The models are constructed with an … idea of prediction models based on the string invariants (PMBSI). The performance of PMBSI is compared to support vector … application based on the deviations from the closed string/pattern form (PMBCS). We found the difference between these two …
