%description
Estimation, scoring, and plotting functions for the semi-parametric factor
model proposed by Liu & Wang (2022) <doi:10.1007/s11336-021-09832-8> and
Liu & Wang (2023) <arXiv:2303.10079>. Both the conditional densities of
observed responses given the latent factors and the joint density of
latent factors are estimated non-parametrically. Functional parameters are
approximated by smoothing splines, whose coefficients are estimated by
penalized maximum likelihood using an expectation-maximization (EM)
algorithm. E- and M-steps can be parallelized on multi-thread computing
platforms that support 'OpenMP'. Both continuous and unordered categorical
response variables are supported.
