Surrogate data (see Surrogate data testing) usually refers to time series data that is produced using well-defined (linear) models like ARMA processes that reproduce various statistical properties like the autocorrelation structure of a measured data set.[1] The resulting surrogate data can then for example be used for testing for non-linear structure in the empirical data.
