MORIE 森

Multi-domain Open Research and Inferential Estimation.

A multi-domain scientific computing toolkit (Python and R) for observational inference, with sociolegal, signal-processing, cryptographic, spatial-statistics, statistical-physics, and psychometrics modules. Hosts the MRM framework as a primary application for Canadian carceral, police, and oversight data analysis.

The R package ships native causal-inference engines — matching (nearest/Mahalanobis/exact/CEM/optimal/genetic/cardinality), double machine learning with clustered SEs, R-learner causal forests, T/S/X/DR meta-learners, design-based GLM, and a causal DAG toolkit (morie_dag*) — implemented in-package and cross-validated against MatchIt, DoubleML, grf, and dagitty rather than depending on them.

import morie checks PyPI once a day for a newer release (fail-silent, cached). Set MORIE_NO_UPDATE_CHECK=1 to disable it.

Installation

Full step-by-step install guide with platform-specific notes (PEP 668 on Debian, python 3.13 segfault on Raspberry Pi OS, etc.) is at INSTALLATION.md.

morie is a Python (and R) package — once Python is present it is pip install morie. If you are starting with nothing installed, INSTALLATION.md opens with Step 1 — install the prerequisites: every tool you might need (Python, curl, bash/WSL, Git Bash, winget, Homebrew, Docker, R) with its official download. The short version:

• Windows — install Python from python.org (on the first screen tick Add python.exe to PATH), then pip install morie. Full walkthrough: Windows below. Windows has no curl/bash, so the one-liner does not apply there.
• macOS / Linux — the one-liner below sets up everything. It needs curl and bash, which macOS has built in and most Linux ships.
• Already have Python ≥3.10 — just pip install morie (on Debian, Ubuntu and Raspberry Pi OS use the venv three-liner below; their system pip refuses to install into /usr). The estimators take a pandas DataFrame, a CSV path, or a dict of columns; pandas is optional (morie ships its own frame core).

For terminal users — one-liner (Linux / macOS / WSL)

The simplest path if you have a terminal with curl and bash — both are built into macOS and preinstalled on most Linux (Windows has no bash, so use the installer above instead). It then bootstraps everything else for you: Python via uv, a managed venv, and the morie wheel. No pre-existing Python or pip needed.

curl -fsSL https://rootcoder007.github.io/morie/install.sh | bash

Or, with R alongside Python:

curl -fsSL https://rootcoder007.github.io/morie/install.sh | bash -s -- --auto

After install, ~/.local/bin/morie is a thin shim into the managed venv at ~/.venvs/morie. Full install instructions, channel comparison, and platform-specific notes are at rootcoder007.github.io/morie/#quick-start.

On minimal Linux containers (Alpine, slim Debian) that ship without curl, install it first: apt-get install -y curl or apk add curl. macOS already has curl built in.

Debian, Ubuntu, Raspberry Pi OS — plain pip in a venv

Debian-family systems mark the system Python "externally managed", so pip install morie stops with an error. A virtual environment is the supported way and needs nothing beyond the stock python3 (add sudo apt-get install -y python3-venv if venv is missing):

python3 -m venv ~/.venvs/morie
source ~/.venvs/morie/bin/activate
pip install -U morie
morie --version

Activate the venv (source ~/.venvs/morie/bin/activate) in each new shell, or call ~/.venvs/morie/bin/morie directly.

Recommended — Windows

Windows doesn't ship curl, bash, python, or R, so the Linux/macOS one-liner above won't run there. The path that works on any Windows with no prerequisites:

1. Install Python from python.org/downloads — on the first installer screen, tick "Add python.exe to PATH" (skipping this is the No. 1 cause of python being "not recognized" in the terminal).
2. (Optional — for the R package) install R from cran.r-project.org/bin/windows/base.
3. Open PowerShell and install morie:

python -m pip install --upgrade pip
python -m pip install morie
python -c "import morie; print(morie.__version__)"

For the R package, install rmorie (the R distribution of morie): Rscript -e "install.packages('rmorie', repos=c('https://rootcoder007.r-universe.dev','https://cloud.r-project.org'))"

Prefer a package manager? If winget --version works on your machine, winget install -e --id Python.Python.3.12 (and RProject.R) installs the prerequisites in one line each — but winget is absent from many Windows installs, so the installer steps above are the reliable default. The full Windows walkthrough, including fixes for common errors (python opening the Microsoft Store, PowerShell execution policy, long-path), is in INSTALLATION.md.

Python — Homebrew (macOS / Linuxbrew)

If you don't have Homebrew yet, install it first (macOS ships curl and bash, so this works out of the box):

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

Then:

brew tap rootcoder007/morie
brew install morie

The tap repo is rootcoder007/homebrew-morie. It pulls morie's source distribution from PyPI and bundles a self-contained python@3.12 venv — no system Python required.

Python — PyPI (manual; requires pip already installed)

pip install morie

Heads-up: modern Debian / Ubuntu / Raspberry Pi OS forbid pip outside virtual environments (PEP 668), and the system python3 on Raspberry Pi OS 13 segfaults on importing the SciPy stack. If pip install morie errors or import morie segfaults, use the one-liner above instead — it handles both cases automatically.

Python — Docker (no local dependencies)

# Latest stable
docker run --rm ghcr.io/rootcoder007/morie:latest morie --help

# Pin to a specific version (recommended for reproducibility)
docker run --rm ghcr.io/rootcoder007/morie:latest morie --help

Multi-arch image published on every release with both versioned and :latest tags. Requires only Docker — no Python, no pip.

R package: rmorie — r-universe (CRAN when available)

The R distribution of morie is the rmorie package.

# Stable from CRAN (when listing is live)
install.packages("rmorie")

# Nightly binary builds (recommended while CRAN listing is rolling out)
install.packages(
  "rmorie",
  repos = c(
    rootcoder007 = "https://rootcoder007.r-universe.dev",
    CRAN     = "https://cloud.r-project.org"
  )
)

Quick start

import morie
from morie.data import load_dataset

# CPADS 2021-22 public-use microdata: fetched from Open Canada on first
# use, then served from the local cache
df = load_dataset("ocp21")
print(df.shape)

# Welch's two-sample t-test, and the guide every morie.fn callable carries
from morie.fn import describe, welcht

result = welcht([5.1, 4.9, 5.6, 5.8, 6.0], [6.2, 6.8, 7.1, 6.5, 7.4])
print(result)
print(describe("welcht"))

AI assistance

MORIE was developed with substantial assistance from frontier AI assistants. The author retains full responsibility for the code, the methods, and the scientific claims; AI assistance accelerated implementation but does not change the attribution of the work.

• Claude — Anthropic. Anthropic's Claude family (Opus, Sonnet, and Haiku across the 4.x generation) was used extensively throughout development for code generation, refactoring, documentation, code review, and design discussions. Use was supported by Anthropic research-credit programs.

• Gemini and Vertex AI — Google. Google's Gemini 2.5 models (Pro and Flash) on the Vertex AI platform were used extensively for additional code generation, cross-checking Claude-generated code, multi-modal data analysis, and prototype evaluation. Use was supported by Google research-credit programs.

Trust model — what the powerful features can do to your machine

morie is a developer/research toolkit with some intentionally powerful surfaces. They run local, user-supplied input by design — never remote or network-supplied code — but under an untrusted-input threat model each is high-impact, so every one defaults to the safe behaviour and gates the risky path behind a single, named, off-by-default environment knob:

morie doctor prints the current state of every knob so you can see the active trust posture at a glance. Only enable a knob for inputs you fully control.
