\details{
\code{sspdsty} is used by \code{\link{ssden}} to compute
cross-validated density estimate with a single smoothing
parameter. \code{mspdsty} is used by \code{\link{ssden}} to compute
cross-validated density estimate with multiple smoothing
parameters.
\code{msphzd} is used by \code{\link{sshzd}} to compute
cross-validated hazard estimate with single or multiple smoothing
parameters.
