ECOTRIM 1.0

ECOTRIM is a specialized tool for temporal disaggregation and benchmarking of economic time series. It helps analysts convert low‑frequency data (such as annual figures) into higher‑frequency estimates (quarterly or monthly) while preserving totals and ensuring statistical consistency. ECOTRIM supports widely used methods, including Denton (proportional and first‑difference variants), Chow–Lin, Fernández, and Litterman, and can work with or without indicator series.

Key capabilities:

• Disaggregate annual series to quarterly or monthly frequencies with accounting constraints preserved
• Benchmark and re‑reference series to new totals or base years
• Compare methods and parameter settings to assess the smoothness and fit of results
• Handle indicator‑based and indicator‑free workflows
• Export outputs for further analysis and reporting

Designed for economists, statisticians, and national accounts professionals, ECOTRIM is well suited to gap‑filling, aligning time series to new benchmarks, and producing coherent, publication‑ready datasets.

ECOTRIM is developed by 2SDA. The most popular version of this product among our users is 1.0. The name of the program executable file is Ecotrim.exe.
