Abstract: | The piece-wise constant hazard rate is presented along with the resulting piece-wise constant exponential model for the life times. Maximum likelihood estimation is considered for the complete life test and a life test censored at a preset time. The estimators are found along with their expected values and variances. An example from industry illustrates the estimation procedure in the special case where only two pieces are used. |
