Downloads all the datasets (you can exclude the daily ones or specify a list of those you are targeting specifically) from Kenneth French's Website at <https://mba.tuck.dartmouth.edu/pages/faculty/ken.french/data_library.html>, process them and convert them to list of 'xts' (time series).

General linear modeling with multiple responses (MANCOVA). An overall p-value for each model term is calculated by the 50-50 MANOVA method by Langsrud (2002) <doi:10.1111/1467-9884.00320>, which handles collinear responses. Rotation testing, described by Langsrud (2005) <doi:10.1007/s11222-005-4789-5>, is used to compute adjusted single response p-values according to familywise error rates and false discovery rates (FDR). The approach to FDR is described in the appendix of Moen et al. (2005) <doi:10.1128/AEM.71.4.2086-2094.2005>. Unbalanced designs are handled by Type II sums of squares as argued in Langsrud (2003) <doi:10.1023/A:1023260610025>. Furthermore, the Type II philosophy is extended to continuous design variables as described in Langsrud et al. (2007) <doi:10.1080/02664760701594246>. This means that the method is invariant to scale changes and that common pitfalls are avoided.

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'.
