{title:Program to calculate parameters for creating a censored normal random variable with specified mean and variance}

{p 8 17 2}{cmd:cnormp} {it:mean} {it:sd} [, {cmdab:c:enspoint(}{it:real}{cmd:)} ]

{title:Description}

{p 4 4 2}
{cmd:cnormp} calculates the mean and standard deviation of the underlying uncensored normal distribution
that when left censored at {it:censpoint} will have the specified {it:mean} and {it:sd}.  The default value
for {it:censpoint} when unspecified is zero.
