The package "Nonparametric Estimation of the Derivatives of a Regression Function" implements the method of Wang and Lin (2015) of estimating the first and second derivatives of a regression function from the original data in the case of an increasing evenly spaced design. The derivative estimates are computed at the design points. The computations are based on the difference quotients. The package also includes the experimental data set on the deflection measurements of a round substrate before and after the thin film deposition. See more details regarding the experiment and data analysis in the article of Savchuk and Volinsky (2020).	npregderiv package
