Changes in version 0.1.0 (2026-03-26)                  

  - Initial release.
  - CPI component decomposition into weighted contributions via
    ik_decompose().
  - Core inflation measures (trimmed mean, weighted median,
    exclusion-based, asymmetric trim) via ik_core(), following Bryan and
    Cecchetti (1994).
  - Sticky vs flexible price decomposition via ik_sticky_flexible(),
    based on Atlanta Fed methodology (Bils and Klenow, 2004).
  - Inflation persistence estimation (sum of AR coefficients, half-life
    via companion matrix, largest root) via ik_persistence().
  - Diffusion indices via ik_diffusion().
  - Phillips curve estimation (traditional, expectations-augmented,
    hybrid) via ik_phillips(). Newey-West HAC standard errors via
    robust_se = "HAC".
  - Breakeven inflation from nominal and real yields via ik_breakeven().
  - Trend inflation extraction (Hodrick-Prescott filter with
    frequency-based lambda, Beveridge-Nelson decomposition, exponential
    smoothing, moving average) via ik_trend().
  - Forecast evaluation (Mincer-Zarnowitz bias, Nordhaus efficiency,
    Diebold-Mariano test) via ik_forecast_eval().
  - Side-by-side comparison of core inflation measures via ik_compare().
  - Built-in sample data via ik_sample_data().
