Type I censoring occurs when the subjects of an experiment are right censored. Type II censoring occurs when the experiment stops after a certain number of subjects have failed; the remaining subjects are then right censored. Special techniques may be used to handle censored data. Tests with specific failure times are coded as actual failures; censored data are coded for the type of censoring and the known interval or limit. Special software programs (often reliability oriented) can conduct a maximum likelihood estimation for summary statistics, confidence intervals, etc. baby footed pajamas 9-12 months WebSep 24, 2024 · We also found that, besides the four main approaches (complete-data analysis method; imputation approach; dichotomizing the data; the likelihood-based approach) to handling censored data, there were several other innovative approaches to handling censored data.
