Enum OrderSelectionMethod 

pub enum OrderSelectionMethod {
    Pacf,
    PacfAnnual,
}

Order selection criterion for autoregressive model fitting.

Controls how the lag order is chosen when fitting a time series model. Two variants are accepted:

• "pacf" — classical periodic Yule-Walker with PACF-based order selection. Default.
• "pacf_annual" — extends "pacf" with an annual component (PAR(p)-A), adding one extra coefficient ψ per (entity, season) that multiplies the rolling 12-month average of past observations.

Variants

Pacf

Periodic Yule-Walker partial autocorrelation method (PACF).

PacfAnnual

Periodic Yule-Walker order selection augmented with an annual component.

When selected, the estimation pipeline performs four steps beyond the classical Self::Pacf path:

1. Extended Yule-Walker fitting — the system is augmented with a cross-correlation term between the current-season inflow and the rolling 12-month average, yielding the annual coefficient ψ alongside the classical AR coefficients.
2. Annual-stats computation — per-season sample mean μ^A and Bessel-corrected standard deviation σ^A of the rolling 12-month average are computed for each hydro plant.
3. Parquet emission — the triple (ψ, μ^A, σ^A) is written to inflow_annual_component.parquet in the output directory.
4. Widened LP lag stride — the noise-column layout in the LP is extended to accommodate the annual term alongside the classical lags.
