denoisr

Overview

denoisr is a non-parametric smoother for noisy curve data, providing different functions to estimate various parameters:

• estimate_H0_list() and estimate_H0_deriv_list() estimate the smoothness of the curves.
• estimate_b_list() and estimate_bandwidth() estimate the bandwidth used in the Nadaraya-Watson estimator.
• estimate_curve() estimates one curve, given bandwidths.
• smooth_curves() and smooth_curves_regularity() estimate the curves.

You can learn more about them in vignette('denoisr').
