%description
Contains functions to perform Bayesian inference using a spectral analysis
of Gaussian process priors. Gaussian processes are represented with a
Fourier series based on cosine basis functions. Currently the package
includes parametric linear models, partial linear additive models
with/without shape restrictions, generalized linear additive models
with/without shape restrictions, and density estimation model. To maximize
computational efficiency, the actual Markov chain Monte Carlo sampling for
each model is done using codes written in FORTRAN 90. This software has
been developed using funding supported by Basic Science Research Program
through the National Research Foundation of Korea (NRF) funded by the
Ministry of Education (no. NRF-2016R1D1A1B03932178 and no.
NRF-2017R1D1A3B03035235).
