Matrix factor reconstruction checklist
StatMedAnalysis | 12 November 2026

Verify dimensions and multiplication order before accepting exported factors.
Record whether transposes are required. Recompute a diagonal and an off-diagonal entry, then measure the full residual. Save the software version and any retained rank.
Use synthetic or aggregate values only. Duplicate the blank row for additional records.

Factorization | Original dimensions | Factor dimensions | Reconstruction equation | Residual norm | Tolerance
________ | ________ | ________ | ________ | ________ | ________

Fictional example: An upper Cholesky factor with rows (2,1),(0,3) reconstructs covariance rows (4,2),(2,10) through transpose-times-factor.
