The identification of solar wind parameters that influence the relativistic electron fluxes by employing a NARMAX OLS-ERR approach

The NARMAX OLS-ERR algorithm, which is widely used in the study of system dynamics, is able to determine the causal relationship between the input and output variables for a wide class of linear and nonlinear systems. This technique has been applied to measurements of the geosynchronous relativistic electron fluxes, provided by Los Alamos National Laboratory, and Solar wind parameters taken from OMNIWeb for the time period from 1989 to 2010. The aim was to identify which of the solar wind parameter had the most influence on the electron fluxes.
