%description
Functions for model-based response dimension reduction. Usual dimension
reduction methods in multivariate regression focus on the reduction of
predictors, not responses.  The response dimension reduction is
theoretically founded in Yoo and Cook (2008)
<doi:10.1016/j.csda.2008.07.029>. Later, three model-based response
dimension reduction approaches are proposed in Yoo (2016)
<doi:10.1080/02331888.2017.1410152> and Yoo (2019)
<doi:10.1016/j.jkss.2019.02.001>. The method by Yoo and Cook (2008) is
based on non-parametric ordinary least squares, but the model-based
approaches are done through maximum likelihood estimation. For two
model-based response dimension reduction methods called principal fitted
response reduction and unstructured principal fitted response reduction,
chi-squared tests are provided for determining the dimension of the
response subspace.
