%description
Generalized factor model is implemented for ultra-high dimensional data
with mixed-type variables. Two algorithms, variational EM and alternate
maximization, are designed to implement the generalized factor model,
respectively. The factor matrix and loading matrix together with the
number of factors can be well estimated. This model can be employed in
social and behavioral sciences, economy and finance, and genomics, to
extract interpretable nonlinear factors. More details can be referred to
Wei Liu, Huazhen Lin, Shurong Zheng and Jin Liu. (2021)
