Local Quasi-Exponential Growth Models: Kernel Differential Equation Regression and Mouse Tumor Growth Data
Chunlei Ge, W. John Braun
Local polynomial regression faces several challenges when dealing with sparse data. The difficulty in capturing local features of the underlying function can lead to a possible mis…
