Shift Analysis for Large Number of Tests

I’m trying to check for run-to-run variation across a large number of tests — e.g. >1,000 tests The data is in long format, with all test values in a single column (TestValues). Each unit has measurements across multiple runs (e.g., WW1, WW2, WW3), identified by a WW column, and we have a UnitID to track which unit it is. I want to: Check if there’s a statistically significant shift across runs f...
