Abstract (2. Language): 
In order to calculate reliability indices of some important equipment, the life data type of equipment or product needs to be ascertained firstly. Aiming to this question, the linear regression and correlation coefficient method is suggested. The linearization of common distribution like as exponential distribution is complied with the principle of linear regression. But for three-parameter Weibull distribution, the location parameter usually cannot be ascertained. A binary search algorithm is programmed to locate the location parameter firstly. Then through the comparison of correlation coefficient, the most fitted distribution type can be found out quickly. The result also shows that the inferred distribution type is in accord with the facts. Example illustrates the effectiveness and validness of linear regression and correlation coefficient for the inference of distribution type of life data.
