No, it doesn't.

Right-censored data are data with (so-called) censored values. E.g. there 
is a newsvendor and he sells newspapers for a week.

Mon: 77
Tue: 56
Wed: 60
Thu: 80
Fri: 85
Sat: 59
Sun: 48

This values are numbers of sold pieces from Monday to Sunday. And he sold 
out newspapers on Wednesday and on Thursday. This is an example of 
right-censored data. He could sold more pieces in that two days.

And I need the variance and mean of data like this.

Thank you!
