Linear-system perturbation record
StatMedAnalysis | 12 November 2026

Record how a specified input change affects a computed solution.
Keep all original values. Change one specified input and solve again. Compare relative changes and residuals without treating conditioning as a statistical score.
Use synthetic or aggregate values only. Duplicate the blank row for additional records.

Matrix/version | Scaling | Original right-hand side | Perturbation | Original solution | New solution | Condition convention
________ | ________ | ________ | ________ | ________ | ________ | ________

Fictional example: Diagonal entries 1 and 0.001 map right-hand side (1,0.001) to solution (1,1).
