No Causal impact libraries require deep econometric and Bayesian statistical expertise to correctly implement structural time-series models, Kalman filters, and counterfactual inference. These mathematical models demand specialized quantitative domain knowledge that LLMs cannot reliably invent or validate without domain experts.
What it would actually take: A proper implementation requires a probabilistic programming framework (such as Stan, PyMC, or custom state-space models in C++/Rust) modeling local linear trends, seasonalities, and regression components with spike-and-slab priors. The hardest part is the numerical stability of MCMC sampling or variational inference combined with correct posterior predictive distribution extraction for counterfactual estimation. It requires an econometrician or statistician experienced in state-space models and Bayesian computation.
