%description
Utilize an orthogonality constrained optimization algorithm of Wen & Yin
(2013) <DOI:10.1007/s10107-012-0584-1> to solve a variety of dimension
reduction problems in the semiparametric framework, such as Ma & Zhu
(2012) <DOI:10.1080/01621459.2011.646925>, Ma & Zhu (2013)
<DOI:10.1214/12-AOS1072>, Sun, Zhu, Wang & Zeng (2019)
<DOI:10.1093/biomet/asy064> and Zhou, Zhu & Zeng (2021)
<DOI:10.1093/biomet/asaa087>. The package also implements some existing
dimension reduction methods such as hMave by Xia, Zhang, & Xu (2010)
<DOI:10.1198/jasa.2009.tm09372> and partial SAVE by Feng, Wen & Zhu (2013)
<DOI:10.1080/01621459.2012.746065>. It also serves as a general purpose
optimization solver for problems with orthogonality constraints, i.e., in
Stiefel manifold. Parallel computing for approximating the gradient is
enabled through 'OpenMP'.
