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

cnormp mean sd [, censpoint(real) ]

Description

cnormp calculates the mean and standard deviation of the underlying uncensored normal distribution
that when left censored at censpoint will have the specified mean and sd. The default value
for censpoint when unspecified is zero.

Examples

drawnorm x, mean(20) sd(20) n(1000) clear

cnormp 20 20

forv i=1/9 {

g y`i'=max(0,rnormal(r(m),r(s)))

}

su

drawnorm x, mean(20) sd(20) n(1000) clear

cnormp 20 20, c(10)

forv i=1/9 {

g y`i'=max(10,rnormal(r(m),r(s)))

}
