Floating Percentile Model with additional functions for optimizing inputs and evaluating outputs and assumptions.

'FRACTRAN' is an obscure yet tantalizing programming language invented by John Conway of 'Game of Life' fame. The code consists of a sequence of fractions. The rules are simple. First, select an integer to initialize the process. Second, multiply the integer by the first fraction. If an integer results, start again with the new integer. If not, try the next fraction. Finally, if no such multiplication yields an integer, terminate the program. For more information, see <https://en.wikipedia.org/wiki/FRACTRAN> .

Assists in statistical model building to find optimal and semi-optimal higher order interactions
    and best subsets. Uses the lm(), glm(), and other R functions to fit models generated from a feasible 
    solution algorithm. Discussed in Subset Selection in Regression, A Miller (2002). Applied and explained
    for least median of squares in Hawkins (1993) <doi:10.1016/0167-9473(93)90246-P>. The feasible solution 
    algorithm comes up with model forms of a specific type that can have fixed variables, higher order 
    interactions and their lower order terms.

Methods and tools for implementing functional singular spectrum analysis and related techniques.

Set of functions that enable you to use the FUSION commands (Program available in: <http://forsys.sefs.uw.edu/fusion/fusionlatest.html>).

Provides and extends the 'Fuzzy Coco' algorithm by wrapping the
    'FuzzyCoCo' 'C++' Library, cf
    <https://github.com/Lonza-RND-Data-Science/fuzzycoco>. 'Fuzzy Coco'
    constructs systems that predict the outcome of a human decision-making
    process while providing an understandable explanation of a possible
    reasoning leading to it.  The constructed fuzzy systems are composed
    of rules and linguistic variables.  This package provides a 'S3' classic
    interface (fit_xy()/fit()/predict()/evaluate()) and a 'tidymodels'/'parsnip'
    interface, a custom engine with custom iteration stop criterion and
    progress bar support as well as a systematic implementation that do
    not rely on genetic programming but rather explore all possible
    combinations.
