\description{ Internal emplik functions }
\details{
These are not intended to be called by the user. 

\code{Wdataclean2} and
\code{DnR} are used by the functions \code{emplikH1.test}, 
\code{emplikH2.test} and \code{emplikdisc.test}.  It is also used by 
\code{LTRC}.  

\code{logelr}, \code{llog}, \code{llogp} and \code{llogpp} 
are used by function \code{el.test}.

\code{Wdataclean2}, \code{WKM} and \code{solve3.QP} are
used by function \code{el.cen.test}. 

\code{Wdataclean2} is used by \code{el.cen.EM}.

\code{LTRC} is for Left Truncated and Right Censored data.

\code{el.test.wt2}, \code{el.test.wt3} are similar to \code{el.test.wt} 
but can take vector mean as constraint. \code{llog}, \code{llogp} and
\code{llogpp} are used by both functions. In addition \code{logwelr}
is used by \code{el.test.wt3}.

\code{iter} is for perform one iteration of EM in the Buckley-James
            censored regression estimation.
\code{redistF} is for redistribution, according to Fdist.
