Summary:In this paper, we point-out a major error in the proofs of the main results of Bahadır Yüzbaşı, Yasin Asar & S. Ejaz Ahmed [(2022). Liu-type shrinkage estimations in linear models, Statistics, 56:2, 396-420]. In particular, the proofs of their Theorems 3.4-3.5 are based on their Lemma 3.2 which is incorrect.
