Statsmodels: Statistical Modeling and Econometrics

Overview

Statsmodels is Python's premier library for statistical modeling, providing tools for estimation, inference, and diagnostics across a wide range of statistical methods. Apply this skill for rigorous statistical analysis, from simple linear regression to complex time series models and econometric analyses.

When to Use This Skill

This skill should be used when:

Fitting regression models (OLS, WLS, GLS, quantile regression)

Performing generalized linear modeling (logistic, Poisson, Gamma, etc.)

Analyzing discrete outcomes (binary, multinomial, count, ordinal)

Conducting time series analysis (ARIMA, SARIMAX, VAR, forecasting)

Running statistical tests and diagnostics

Testing model assumptions (heteroskedasticity, autocorrelation, normality)

Detecting outliers and influential observations

Comparing models (AIC/BIC, likelihood ratio tests)

Estimating causal effects

Producing publication-ready statistical tables and inference
