چکیده
|
The present study proposes several methods for improving the parameter estimation of interval-censored exponential lifetime data. these methods can be regarded as the versions of substitution method which are based on the most probable time of occurring failures or the meantime of failures in each inspection interval. based on simulation studies, the methods proposed in this present study can improve the existing estimators which are based on the midpoint of inspection intervals or the exponential probability plot.
