`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](https://www.doi.org/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](https://parastlab.shinyapps.io/MonotonicityTest/).
