In this paper, we consider the estimation problem of the unknown link function in the nonparametric multiplicative regression model. Combining the penalized splines technique, a least product relative error estimation method is proposed, where a effective model degree of freedom is defined, then the smoothing parameter is chosen by some information criterions. Simulation studies show that these strategies work well. Some asymptotic properties are established. A real data set is analyzed to illus...

Fibrosarcoma (FS) is a rare, highly aggressive tumor that results from pathological changes in spindle-shaped fibroblasts that divide at an extremely rapid rate. Typically, it manifests as a painless mass usually in the upper and lower extremities, with varying symptoms based on its location and size. Diagnosis of spindle-shaped FS tumor is nearly often one of exceptions due to it is rarity and variability. As a consequence, misdiagnosis of similar tumor types is prevalent and often leading to a...

Univariate linear regression mainly studies the linear correlation between two variables. This article mainly selects Shandong Province’s total social fixed asset investment and regional gross product (GDP) as variables to explore the relationship between the two from 1975 to 2017, and performs a regression analysis. The results show that there is a positive correlation between the two, and Shandong Province’s whole-society fixed asset investment has a positive prediction effect on Shandong Prov...
