ml-learnkit 0.1.5

Machine Learning and Statistical Analysis Toolkit

ml-learnkit

A lightweight Python toolkit for machine learning and statistical analysis, designed for education. It exposes every intermediate calculation so you can follow along with the maths, not just get an answer.

Features

Load raw Python lists into structured data objects with tabular display. Build a simple linear regression model from first principles without black-box estimators. Access regression coefficients with standard errors, t-statistics, and p-values. Generate ANOVA tables with all sum-of-squares and mean-square decompositions. Render six diagnostic plots in a single call with 95% confidence bands, residual analysis, and influence diagnostics via seaborn.

Installation

Install from PyPI:

pip install ml-learnkit

Requires Python > 3.10.

Quick Start

from ml_learnkit import Reader, SimpleLinearRegressor, Split

# Load data
reader = Reader()
data = reader.read_lists(
    lists=[[1, 2, 3, 4, 5], [2.1, 4.0, 5.9, 8.2, 9.8]],
    columns=["X", "Y"]
)

# Inspect
data.show()

# Split data
split = Split()
dataset = split.split(data.get("X"), data.get("Y"), test_size=0.4)

# Fit model on train set
model = SimpleLinearRegressor()
model.fit(dataset["X_train"], dataset["y_train"])

# Test model on hold-out set
test_results = model.test(dataset["X_test"], dataset["y_test"])

# View results
print(model.equation())
print(test_results)
model.regression_table()
model.anova()
model.plot()

Core Concepts

ml-learnkit implements ordinary least squares (OLS) regression with full transparency. Every calculation step is exposed: computation worksheets, intermediate sums of squares, standard errors, test statistics, and diagnostic plots. This educational design lets you verify each result against your own calculations or textbook examples.

The toolkit computes:

Regression coefficients (intercept b₀ and slope b₁), standard errors and t-statistics for both coefficients, two-tailed p-values from the t-distribution, ANOVA decomposition (SSR, SSE, SST, MSR, MSE, F-statistic), and six diagnostic plots (fitted line, residuals, Q-Q, scale-location, leverage, histogram).
