</span><b><span lang="EN-US" style="font-family:"Times New Roman","serif"">Abstract:</span></b><span lang="EN-US" style="font-family:"Times New Roman","serif""> This paper develops a
bias correction scheme for reparameterized inverse gamma regression models with
varying precision, which is tailored to situations where the response variable
has an asymmetrical shape on the positive real line. In particular, we discuss
maximum likelihood estimation for the model parameters and derive closed-form
expressions for the first-order bias of the estimators. The expressions derived
are simple and only require the definition of a few matrices. This enables us
to obtain corrected estimators that are approximately unbiased. We conduct an
extensive Monte Carlo simulation study to evaluate the performance of the
proposed corrected estimators. Finally, we apply the results obtained in three
real-world datasets. </span><span style="font-family:"Times New Roman","serif"">(*In
