lspartition - Nonparametric Estimation and Inference Procedures using
Partitioning-Based Least Squares Regression
Tools for statistical analysis using partitioning-based
least squares regression as described in Cattaneo, Farrell and
Feng (2020a, <doi:10.48550/arXiv.1804.04916>) and Cattaneo,
Farrell and Feng (2020b, <doi:10.48550/arXiv.1906.00202>):
lsprobust() for nonparametric point estimation of regression
functions and their derivatives and for robust bias-corrected
(pointwise and uniform) inference; lspkselect() for data-driven
selection of the IMSE-optimal number of knots; lsprobust.plot()
for regression plots with robust confidence intervals and
confidence bands; lsplincom() for estimation and inference for
linear combinations of regression functions from different
groups.
