%description
Produces power spectral density estimates through iterative refinement of
the optimal number of sine-tapers at each frequency. This optimization
procedure is based on the method of Riedel and Sidorenko (1995), which
minimizes the Mean Square Error (sum of variance and bias) at each
frequency, but modified for computational stability. The same procedure
can now be used to calculate the cross spectrum (multivariate analyses).
