Implements numerical entropy-pooling for portfolio construction and 
    scenario analysis as described in Meucci, Attilio (2008) and Meucci, Attilio (2010) 
    <doi:10.2139/ssrn.1696802>.

Helps access various Fantasy Football APIs by handling
    authentication and rate-limiting, forming appropriate calls, and
    returning tidy dataframes which can be easily connected to other data
    sources.

The 'fftab' package stores Fourier coefficients in a tibble and 
  allows their manipulation in various ways. Functions are available for converting 
  between complex, rectangular ('re', 'im'), and polar ('mod', 'arg') representations, 
  as well as for extracting components as vectors or matrices. Inputs can include 
  vectors, time series, and arrays of arbitrary dimensions, which are restored 
  to their original form when inverting the transform. Since 'fftab' stores Fourier 
  frequencies as columns in the tibble, many standard operations on spectral data 
  can be easily performed using tidy packages like 'dplyr'.

Create, visualize, and test fast-and-frugal decision trees (FFTs) using the algorithms and methods described by Phillips, Neth, Woike & Gaissmaier (2017), <doi:10.1017/S1930297500006239>. 
    FFTs are simple and transparent decision trees for solving binary classification problems. 
    FFTs can be preferable to more complex algorithms because they require very little information, are easy to understand and communicate, and are robust against overfitting.

Provides a simple and efficient wrapper around the fastest
        Fourier transform in the west (FFTW) library <http://www.fftw.org/>.

Provides a wrapper for several 'FFTW' functions. This package provides access to the two-dimensional 'FFT', the multivariate 'FFT', and the one-dimensional real to complex 'FFT' using the 'FFTW3' library. The package includes the functions fftw() and mvfftw() which are designed to mimic the functionality of the R functions fft() and mvfft(). The 'FFT' functions have a parameter that allows them to not return the redundant complex conjugate when the input is real data.
