As mentioned by Lundbergh, Terasvirta, and van Dijk (2003), ample empirical evidence exists for both structural breaks and non-linearity
in the dynamic properties of many macroeconomic series.
This method improves quality of response surface in terms of capturing non-linearity
in whole design space.
In general, non-linearity
can be captured by Threshold Autoregressive (TAR), Hamilton's Markov switching (1989) and the smooth transition autoregressive (STAR) models.
Before showing examples of non-linearity
the time series from the station located in a tectonically stable region will be presented.
Table 5 gives the outcome when we adjust for thin trading and include non-linearity
into the model.
El-Naggar and Novak (1994) improved the model of Randolph and Simons (1986) by adding the base hysteresis and non-linearity
The presentation will include stiffness, incompressibility and non-linearity
effects and damping of elastomer mounts.
We start from noting that the detector algorithm includes a memoryless non-linearity
Alstom will work with Aston's Non-Linearity
and Complexity Research Group, which has a long-established reputation in the analysis of complex data and systems using various techniques including methods adopted from statistical physics.
At its slow scan speed of 45 kHz, this -60 C detector offers a dynamic range (92.5 dB in image mode) and has a low readout noise and non-linearity
The most striking finding was that the non-linearity
of the cochlea, that was strongly reduced in the group without NAC, as manifested by the PMTF-results, was practically unchanged in the NAC-group throughout the study.
