The authors analyze the auroral electrojet index for the days 30-31 October 1978 as the output of a nonlinear system driven by various aspects of the interplanetary magnetic field (IMF) and solar wind (speed and density). The nonlinear input/output analysis takes the form of a prediction scheme; they compare the results to an autoregressive (linear) predictor and to a nonlinear predictor based only on the output signal. Different combinations of the solar wind variables are used as input functions. They find that only a few of the input combinations show any evidence whatsoever for nonlinear coupling between the input and the output for this interval. 53 refs., 10 figs., 1 tab.
