TY - JOUR AB - A technique, called forecast entropy, is proposed to measure the difficulty of forecasting data from an observed time series. When the series is chaotic, this technique can also determine the delay and embedding dimension used in reconstructing an attractor. An ideal random system is defined. An observed time series from the Lorenz system is used to show the results. VL - 33 IS - 5/6 SN - 0368-492X DO - 10.1108/03684920410534056 UR - https://doi.org/10.1108/03684920410534056 AU - Yao W.
