pathmc

Bayesian path analysis (observed-variable SEM) in PyMC. Compiles a lavaan-inspired formula DSL into a generative PyMC model, then layers introspection, identification diagnostics, the `do()` operator, and causal estimands (ATE/CATE/ATT/ATU/prob) on top. Use when the user asks to specify, fit, or query a Bayesian structural causal model; estimate average treatment effects via g-computation; check identification with adjustment sets or the front-door criterion; or simulate panel/longitudinal counterfactuals.
