The power of surrogate data testing with respect to non-stationarity
J. Timmer
Surrogate data testing is a method frequently applied to evaluate the results of nonlinear time series analysis. Since the null hypothesis tested against is a linear, gaussian, sta…
Cross-spectral analysis of physiological tremor and muscle activity. II. Application to synchronized EMG
J. Timmer, M. Lauk, W. Pfleger +1
We investigate the relationship between synchronized muscle activity and tremor time series in (enhanced) physiological tremor by cross-spectral analysis. Special attention is dire…
Cross-spectral analysis of physiological tremor and muscle activity. I. Theory and application to unsynchronized EMG
J. Timmer, M. Lauk, W. Pfleger +1
We investigate the relationship between the extensor electromyogram (EMG) and tremor time series in physiological hand tremor by cross-spectral analysis. Special attention is direc…
Testing the Markov condition in ion channel recordings
J. Timmer, S. Klein
A statistical test is presented to decide whether data are adequately described by probabilistic functions of finite state Markov chains (''hidden Markov models'') as applied in th…
