GALM

Residual validation

Upload synchronized residual series and receive a model-agnostic diagnostic scorecard: no signup, no model specification.

What to upload

  • Synchronized residual columns, one header per series
  • CSV or tab-delimited TXT
  • Optional date column (YYYY-MM-DD); otherwise a synthetic daily timeline is used

Not required

  • No GALM model or calibration spec
  • No parametric fit (ARMA/GARCH orders, LL/AIC/BIC)
  • No returns or factor exposures: residuals only

Checks run on your upload: ARCH-LM, Ljung–Box, Jarque–Bera (when applicable), and synchronized cross-sectional dependence.

CSV or TXT (tab delimited) residual series, up to 25MB

Expected format

One column per residual stream with a header label; rows must be synchronized across columns (same observation count). Every row must have the same number of columns.

Free validation: files are processed in memory; uploaded residuals are not stored on our servers after your session.

White-label report (paid): report and client details are stored temporarily until your PDF is delivered by email, then deleted.
