Simplifies the creation of reproducible data science environments
    using the 'Nix' package manager, as described in
    Dolstra (2006) <ISBN 90-393-4130-3>. The included `rix()`
    function generates a complete description of the environment as a
    `default.nix` file, which can then be built using 'Nix'. This results in
    project specific software environments with pinned versions of R, packages,
    linked system dependencies, and other tools or programming languages such
    as Python or Julia. Additional helpers make it easy to run R code in
    'Nix' software environments for testing and production.

Streamlines the creation of reproducible analytical pipelines using
  'default.nix' expressions generated via the 'rix' package for reproducibility. Define
  derivations in 'R', 'Python' or 'Julia', chain them into a composition of pure
  functions and build the resulting pipeline using 'Nix' as the underlying
  end-to-end build tool. Functions to plot the pipeline as a directed acyclic
  graph are included, as well as functions to load and inspect intermediary results
  for interactive analysis. User experience heavily inspired by the 'targets' package.

Jade is a high performance template engine heavily influenced by
    Haml and implemented with JavaScript for node and browsers.

Personalized assignment to one of many treatment arms via regularized and clustered joint assignment forests as described in Ladhania, Spiess, Ungar, and Wu (2023) <doi:10.48550/arXiv.2311.00577>. The algorithm pools information across treatment arms: it considers a regularized forest-based assignment algorithm based on greedy recursive partitioning that shrinks effect estimates across arms; and it incorporates a clustering scheme that combines treatment arms with consistently similar outcomes.

Jalali calendar, or solar Hijri, is calendar of Iran and
    Afghanistan (<https://en.wikipedia.org/wiki/Solar_Hijri_calendar>).
    This package is designed to working with Jalali date. For this
    purpose, It defines JalaliDate class that is similar to Date class.
