Use scikit-learn for ML; statistical-analysis for test choice.\"\nlicense: \"BSD-3-Clause\"\n---\n\n# statsmodels\n\n## Overview\n\nStatsmodels provides classical statistical modeling with rigorous inference for Python. It covers linear models, generalized linear models, discrete choice, time series, and comprehensive diagnostics. Unlike scikit-learn (prediction-focused), statsmodels emphasizes coefficient interpretation, p-values, confidence intervals, and model diagnostics.\n\n## When to Use\n\n- Fitting linear regression (OLS, WLS, GLS) with detailed coefficient tables and diagnostics\n- Running logistic regression with odds ratios and marginal effects for clinical/epidemiological studies\n- Analyzing count data with Poisson or negative binomial regression\n- Time series forecasting with ARIMA, SARIMAX, or exponential smoothing\n- Performing ANOVA, t-tests, or non-parametric tests with proper corrections\n- Testing model assumptions (heteroskedasticity, autocorrelation, normality of residuals)\n- Model comparison using AIC/BIC or likelihood ratio tests\n- Using R-style formula interface (`y ~ x1 + x2 + C(group)`) for intuitive model specification\n- For prediction-focused ML with cross-validation and hyperparameter tuning, use `scikit-learn` instead\n- For Bayesian modeling with posterior inference, use `pymc` instead\n\n## Prerequisites\n\n- **Python packages**: `statsmodels`, `numpy`, `pandas`, `scipy`\n- **Optional**: `matplotlib` (for diagnostic plots), `patsy` (for formula API, included with statsmodels)\n- **Data**: Tabular data as pandas DataFrames or NumPy arrays\n\n```bash\npip install statsmodels numpy pandas matplotlib\n```\n\n## Quick Start\n\n```python\nimport statsmodels.api as sm\nimport statsmodels.formula.api as smf\nimport pandas as pd\nimport numpy as np\n\n# Generate sample data\nnp.random.seed(42)\nn = 100\ndf = pd.DataFrame({\n    \"x1\": np.random.randn(n),\n    \"x2\": np.random.randn(n),\n    \"group\": np.random.choice([\"A\", \"B\"], n)\n})\ndf[\"y\"] = 2 + 3 * df[\"x1\"] - 1.5 * df[\"x2\"] + np.random.randn(n)\n\n# OLS with formula API (R-style)\nresults = smf.ols(\"y ~ x1 + x2 + C(group)\", data=df).fit()\nprint(results.summary())\nprint(f\"R²: {results.rsquared:.3f}, AIC: {results.aic:.1f}\")\n```\n\n## Core API\n\n### Module 1: Linear Regression (OLS, WLS, GLS)\n\nStandard linear models with comprehensive diagnostics.\n\n```python\nimport statsmodels.api as sm\nimport numpy as np\n\n# Generate data\nnp.random.seed(42)\nX = np.random.randn(200, 3)\ny = 1 + 2*X[:, 0] -
