linfinity_depth

The L-infinity depth is a simple generalization of the \(L^p\) multivariate depth to
functional data proposed in Long and Huang (2015)
 <a href="https://arxiv.org/abs/1506.01332">&lt;arXiv:1506.01332</a> and also
used in Dai et al. (2020) tools:::Rd_expr_doi("10.1016/j.csda.2020.106960").

A collection of functions for outlier detection in functional data analysis.
Methods implemented include directional outlyingness by
Dai and Genton (2019) <doi:10.1016/j.csda.2018.03.017>,
MS-plot by Dai and Genton (2018) <doi:10.1080/10618600.2018.1473781>,
total variation depth and modified shape similarity index by
Huang and Sun (2019) <doi:10.1080/00401706.2019.1574241>, and sequential transformations by
Dai et al. (2020) <doi:10.1016/j.csda.2020.106960 among others. Additional outlier detection
tools and depths for functional data like functional boxplot, (modified) band depth etc.,
are also available.
