US trimmed-mean inflation signals (Dallas Fed underlying-inflation gauges)

Monthly underlying-inflation signals from the Dallas Fed trimmed-mean PCE rate (redistributed by FRED, 1977-01 ->): 3-month momentum, 30-month change volatility, 3-sigma anomaly flags vs a trailing 12-month baseline, naive-drift 1-month forecasts, cross-series ranks, the trimmed-mean-vs-headline and trimmed-mean-vs-core PCE spreads, and above-target (>2%) / high-underlying (>3%) regime flags. All rows are normalized to country_code USA so they join cleanly with US macro data. Raw series: Federal Reserve Bank of St. Louis (FRED); underlying data: Federal Reserve Bank of Dallas, U.S. Bureau of Economic Analysis.
