Claim 5:
6. The method of claim 5, wherein:
producing the first matrix comprises storing the set of time-shifted time series as columns in the first matrix; and
the first truncation comprises truncating the columns of the first matrix to remove from a bottom of the first matrix a number of rows equal to the product of the first delay embedding parameter, decremented by one, times the second delay embedding parameter;
the resampling comprises resampling column-wise the second matrix and the second truncation comprises removing from the third matrix a number of columns as a function of a variance of the columns of the third matrix; and
computing a column-wise norm vector and an entry-wise sign-vector of the resampled truncated matrix, and producing a vector equal to the scalar product of the entry-wise norm vector times the entry-wise sign-vector.
