The cenboxplot function uses cenros to estimate the censored values. The cenros function requires at least 2 uncensored observations to be able to do the regression. The cenros function does issue a warning when there are more than 80% censored data, but that is suppressed in cenboxplot.
Dave, I've seen the cenros warning when there are > 80% censored data, and now understand that I don't see the same warning with cenboxplot. Knowing now that I need at least 2 uncensored observations answers my question; some of the constituents have only a single uncensored value. Others have none, and I knew those could not be analyzed or plotted.
Hope this helps.
Most certainly does!
