Study on software reliability growth model

The reliability growth models for software were studied. The MLE of the parameters for the exponential reliability growth model were given. The result shows that the Exponential model is useful for the data containing small samples. The model and the estimation method were applied to a data set. Compared with the Duane and AMSAA model, the estimators of the parameters and MTBF of ERGII has the precision to some extent. Furthermore, the model and the estimation of the parameters are applicable for small sample data.
