#' Bayesian nonparametric density estimation
#'
#' This package performs Bayesian nonparametric density estimation for exact
#' and censored data via a normalized random measure mixture model. The package
#' allows the user to specify the mixture kernel, the mixing normalized measure
#' and the choice of performing fully nonparametric mixtures on locations and
#' scales, or semiparametric mixtures on locations only with common scale
#' parameter. Options for the kernels are: two kernels with support in the real
#' line (gaussian and double exponential), two more kernels in the positive
#' line (gamma and lognormal) and one with bounded support (beta). The options
#' for the normalized random measures are members of the class of normalized
#' generalized gamma, which include the Dirichlet process, the normalized
#' inverse gaussian process and the normalized stable process. The type of
#' censored data handled by the package is right, left and interval.

#' MixNRMI1, MixNRMI2, MixNRMI1cens and MixNRMI2cens which implement
#' semiparametric and fully nonparametric mixtures for exact data, and
#' semiparametric and fully nonparametric mixtures for censored data
#' respectively. Additionally, the package includes several other functions
#' required for sampling from conditional distributions in the MCMC
#' implementation. These functions are intended for internal use only.
