A Julia package for frequency domain analysis of time series

When doing exploratory analysis of time series, frequency domain methods, that is, statistical methods that display information about the temporal correlations of one or more time series in terms of frequencies, can be used to infer physical mechanisms for underlying process dynamics in e.g. geophysical time series, medical time series, etc.). The multitaper method, which leverages Slepian functions to estimate power spectral densities, coherences, and so forth, is implemented here for application to univariate, multivariate, and higher-dimensional (e.g. space-time) processes.

See documentation below.
