Enhancing liu-type estimation for poisson-modified quasi-lindley regression
This study develops an improved Liu‑type estimator for the Poisson‑modification of the quasi‑Lindley regression model (PMQL‑RM) to handle overdispersed count data in the presence of severe multicollinearity. We first formulate the PMQL‑RM and review existing shrinkage estimators, including the PMQL ridge estimator, t...
