MonotonicityTest

MonotonicityTest is an R package thart implements nonparametric bootstrap tests for detecting monotonicity in regression functions from Hall, P. and Heckman, N. (2000) doi:10.1214/aos/1016120363. The function includes tools for visualizing results using Nadaraya-Watson kernel regression and supports efficient computation with 'C++'. More details on this package will be available in Huynh D and Parast L. "MonotonicityTest: An R Package for Efficient Nonparametric Monotonicity Testing." (Under Review)

We also have a shiny app implementing these methods here.
