A principal-weighted penalized regression model and its application in economic modeling.

This paper introduces a novel Principal-Weighted Penalized (PWP) regression model, designed for dimensionality reduction in large datasets without sacrificing essential information. This new model retains the favorable features of the principal component analysis (PCA) technique and penalized regression models. It weighs the variables in a large data set based on their contributions to principal components identified by PCA, enhancing its capacity to uncover crucial hidden variables.

Diabetes mellitus secondary to growth hormone-secreting pituitary adenoma.

Growth hormone-secreting pituitary adenoma is a common intracranial benign tumor, characterized by excessive production of growth hormone, which leads to acromegaly or giant disease.
