Recent research has addressed different facets of an iterative procedure called median polish. The question of verifying if any median polish fit is also an \(L_ 1\) solution, i.e., which also minimizes the sum of absolute deviations, has not been addressed in the recent literature. This note will show that well-known results can be used to verify this equivalence.
