A study on the Parameter Estimation of the Weibull Distribution using Computer Graphic Method
Computer Graphic에 의한 와이블분포 모수추정에 관한 연구
Abstract
This study deals with the estimation of the Weibull parameters, which have a close relation with product reliability characteristics. Among the many kinds of estimation methods, Kao's Weibull Probability Paper(WPP) is commonly used. The WPP is very convenient, but it has a great disadvantage in estimation accuracy by plotting method. It is very difficult to get the same results even if one use the same data several times. A computer program for the regression method is used for the parameter estimation to reduce these errors. Especially, the computer graphic program was written in GW-BASIC 3.22 language and the program appears in the appendix part with a couple of running examples for user's reference.
