“…Te maximum likelihood estimation (MLE) is commonly used for parameter estimation in BRMs, but if the independent variables are ill-conditioned, the results may be unsatisfactory. Te variable selection methods, such as adjusted R 2 [6] or the swarm optimization method [7], can help to deal with this issue. However, this issue often necessitates the use of biased estimators, such as Stein-type estimators [8], ridge estimators [9,10], modifed ridge-type estimators [11], Liu estimators [12,13], two-parameter estimators [14], Dawoud-Kibria estimators [15], and also Liu-type estimators [16,17] which is of particular interest in this paper.…”
