Hierarchical, logistic, GP variants; predictive checks.\"\nlicense: \"Apache-2.0\"\n---\n\n# PyMC Bayesian Modeling\n\n## Overview\n\nPyMC is a Python library for Bayesian statistical modeling and probabilistic programming. It provides an expressive syntax for defining probabilistic models and efficient inference via MCMC (NUTS) and variational methods (ADVI). This skill covers the full Bayesian modeling cycle from model specification through diagnostics, comparison, and prediction.\n\n## When to Use\n\n- Estimating parameters with full uncertainty quantification (credible intervals, not just point estimates)\n- Fitting hierarchical/multilevel models to grouped or nested data\n- Performing prior and posterior predictive checks to validate model assumptions\n- Comparing candidate models using information criteria (LOO-CV, WAIC)\n- Building regression models (linear, logistic, Poisson) in a Bayesian framework\n- Handling missing data or measurement error as latent parameters\n- Modeling time series with autoregressive or random walk priors\n- Generating posterior predictions for new observations with uncertainty bounds\n- Use **Stan/PyStan** instead for compiled, more scalable Bayesian inference on large models; use **statsmodels** for frequentist statistical tests\n\n## Prerequisites\n\n- **Python packages**: `pymc >= 5.0`, `arviz`, `numpy`, `matplotlib`\n- **Data**: NumPy arrays or pandas DataFrames with numeric columns\n- **Environment**: CPU sufficient for most models; GPU via JAX backend for large models\n\n```bash\npip install pymc arviz numpy matplotlib\n# Optional: JAX backend for GPU acceleration\npip install pymc[jax]\n```\n\n## Quick Start\n\n```python\nimport pymc as pm\nimport arviz as az\nimport numpy as np\n\n# Simulate data\nnp.random.seed(42)\nX = np.random.randn(100)\ny = 2.5 + 1.3 * X + np.random.randn(100) * 0.5\n\n# Build and fit model\nwith pm.Model() as model:\n    alpha = pm.Normal(\"alpha\", mu=0, sigma=5)\n    beta = pm.Normal(\"beta\", mu=0, sigma=5)\n    sigma = pm.HalfNormal(\"sigma\", sigma=1)\n    mu = alpha + beta * X\n    y_obs = pm.Normal(\"y_obs\", mu=mu, sigma=sigma, observed=y)\n    idata = pm.sample(1000, tune=1000, chains=4, random_seed=42)\n\nprint(az.summary(idata, var_names=[\"alpha\", \"beta\", \"sigma\"]))\n# Expected: alpha ~ 2.5, beta ~ 1.3, sigma ~ 0.5\n```\n\n## Workflow\n\n### Step 1: Prepare Data\n\nStandardize continuous predictors for better sampling efficiency. Use named coordinates for readable models and ArviZ integration.\n\n```python\nimport pymc as pm\nimport arviz as az\nimport numpy as np\n\n# Load data\nX = np.random.randn(200, 3)  # 200 obs, 3 predictors\ny = X @ np.array([1.0, -0.5, 0.3]) + np.random.randn(200) * 0.8\n\n# Standardize predictors\nX_mean, X_std = X.mean(axis=0), X.std(axis=0)\nX_scaled = (X - X_mean) / X_std\n\n# Define coordinates for named dimensions\ncoords = {\n    \"predictors\": [\"var1\", \"var2\", \"var3\"],\n    \"obs_id\": np.arange(len(y)),\n}\nprint(f\"Data shape: X={X_scaled.shape}, y={y.shape}\")\n```\n\n### Step 2: Define Model and Set Priors\n\nSpecify the model structure inside a `pm.Model()` context. Use weakly informative priors, `dims` for named dimensions, and `HalfNormal` or `Exponential` for scale parameters.\n\n```python\nwith pm.Model(coords=coords) as model:\n    # Priors — weakly informative, not flat\n    alpha = pm.Normal(\"alpha\", mu=0, sigma=1)\n    beta = pm.Normal(\"beta\", mu=0, sigma=1, dims=\"predictors\")\n    sigma = pm.HalfNormal(\"sigma\", sigma=1)\n\n    # Linear predictor\n    mu = alpha + pm.math.dot(X_scaled, beta)\n\n    # Likelihood\n    y_obs = pm.Normal(\"y_obs\", mu=mu, sigma=sigma, observed=y, dims=\"obs_id\")\n\n# Inspect model variables\nprint(model.basic_RVs)  # Lists: [alpha, beta, sigma, y_obs]\n```\n\n### Step 3: Prior Predictive Check\n\nValidate that priors produce plausible data ranges before fitting. Adjust priors if simulated data is unreasonable.\n\n```python\nwith model:\n    prior_pred = pm.sample_prior_predictive(samples=1000, random_seed=42)\n\n# Check prior-implied data range\nprior_y = prior_pred.prior_predictive[\"y_obs\"].values.flatten()\nprint(f\"Prior predictive range: [{prior_y.min():.1f}, {prior_y.max():.1f}]\")\nprint(f\"Observed data range:    [{y.min():.1f}, {y.max():.1f}]\")\n\naz.plot_ppc(prior_pred, group=\"prior\", num_pp_samples=100)\n```\n\n### Step 4: Sample Posterior (MCMC)\n\nRun NUTS sampling with multiple chains. Include `log_likelihood=True` if you plan model comparison later.\n\n```python\nwith model:\n    idata = pm.sample(\n        draws=2000,\n        tune=1000,\n        chains=4,\n        target_accept=0.9,\n        random_seed=42,\n        idata_kwargs={\"log_likelihood\": True},\n    )\n\nprint(f\"Posterior shape: {idata.posterior['beta'].shape}\")\n# Expected: (4 chains, 2000 draws, 3 predictors)\n```\n\n### Step 5: Diagnose Sampling\n\nCheck convergence before interpreting results. All three diagnostics (R-hat, ESS, divergences) must pass.\n\n```python\n# Summary with convergence diagnostics\nsummary = az.summary(idata, var_names=[\"alpha\", \"beta\", \"sigma\"])\nprint(summary[[\"mean\", \"sd\", \"hdi_3%\", \"hdi_97%\", \"r_hat\", \"ess_bulk\"]])\n\n# R-hat convergence check\nbad_rhat = summary[summary[\"r_hat\"] > 1.01]\nif len(bad_rhat) > 0:\n    print(f\"WARNING: {len(bad_rhat)} parameters with R-hat > 1.01\")\n    print(bad_rhat[[\"r_hat\"]])\n\n# Effective sample size check\nlow_ess = summary[summary[\"ess_bulk\"] < 400]\nif len(low_ess) > 0:\n    print(f\"WARNING: {len(low_ess)} parameters with ESS < 400\")\n\n# Divergence check\nn_div = idata.sample_stats.diverging.sum().item()\ntotal = len(idata.posterior.draw) * len(idata.posterior.chain)\nprint(f\"Divergences: {n_div}/{total} ({n_div / total * 100:.2f}%)\")\n\n# Visual diagnostics — trace plots and rank plots\naz.plot_trace(idata, var_names=[\"alpha\", \"beta\", \"sigma\"])\naz.plot_rank(idata, var_names=[\"alpha\", \"beta\", \"sigma\"])\n```\n\n### Step 6: Posterior Predictive Check\n\nValidate model fit by comparing simulated data from the posterior to observed data.\n\n```python\nwith model:\n    pm.sample_posterior_predictive(idata, extend_inferencedata=True, random_seed=42)\n\naz.plot_ppc(idata, num_pp_samples=100)\n# Blue = observed data, grey = posterior simulations\n# Systematic deviations indicate model misspecification\n```\n\n### Step 7: Compare Models\n\nUse LOO-CV or WAIC to compare candidate models. Lower information criterion is better.\n\n```python\n# Fit multiple models with log_likelihood=True, then compare\n# Example: compare linear vs a second model\nidatas = {\"linear\": idata}  # add more fitted models here\n\ncomparison = az.compare(idatas, ic=\"loo\")\nprint(comparison[[\"rank\", \"elpd_loo\", \"p_loo\", \"d_loo\", \"weight\"]])\n\n# Check LOO reliability via Pareto-k diagnostics\nloo_result = az.loo(idata, pointwise=True)\nhigh_k = (loo_result.pareto_k > 0.7).sum().item()\nprint(f\"Observations with Pareto-k > 0.7: {high_k}\")\n# Interpretation: Dloo < 2 = similar models; Dloo > 10 = strong evidence\n\naz.plot_compare(comparison)\n```\n\n### Step 8: Generate Predictions\n\nProduce posterior predictions for new data with full uncertainty propagation.\n\n```python\nX_new = np.array([[0.5, -1.0, 0.2]])\nX_new_scaled = (X_new - X_mean) / X_std\n\nwith model:\n    pm.set_data({\"X_scaled\": X_new_scaled})\n    post_pred = pm.sample_posterior_predictive(\n        idata.posterior, var_names=[\"y_obs\"], random_seed=42\n    )\n\ny_pred = post_pred.posterior_predictive[\"y_obs\"]\nprint(f\"Predicted mean: {y_pred.mean().item():.3f}\")\nprint(f\"94% HDI: {az.hdi(y_pred, hdi_prob=0.94).values}\")\n```\n\n## Key Parameters\n\n| Parameter | Default | Range / Options | Effect |\n|-----------|---------|-----------------|--------|\n| `draws` | `1000` | `500`-`10000` | Number of posterior samples per chain |\n| `tune` | `1000` | `500`-`5000` | Warmup iterations (discarded);
