今回も品質管理に関する記事を記載いたします。 はじめに ワイブル分布（Weibull distribution）は、寿命データや故障時間を扱う分野で最も広く使われている分布の一つです。部品や機械の寿命、材料の強度にも応用されます。 本記事では、下記について ...

Weibull regression model is one of the most popular forms of parametric regression model that it provides estimate of baseline hazard function, as well as coefficients for covariates. Because of ...

This example compares the use of three-parameter and two-parameter Weibull Q-Q plots for the failure times in months for 48 integrated circuits. The times are assumed to follow a Weibull distribution.

Abstract: In this paper a example is discussed to obtain the shape and scale parameters of Weibull distribution. Parameters are estimated using sample time-to-failure data or lifetime data. There are ...

This example considers a data set given in Lawless (1982). The data are the number of days it took rats painted with a carcinogen to develop carcinoma. The last two observations are censored. Maximum ...

Using the Weibull distribution to model gold wire bonding on ENEPIG. The most used distribution in reliability analysis may be the Weibull distribution. Its genesis can be traced back to Waloddi ...

Three-parameter Weibull distribution is one of the preferable distribution models to describe product life. However, it is difficult to estimate its location parameter in the situation of a small size ...

This paper is devoted to study a new generalization of the flexible Weibull with three parameters. This model is referred to as the exponential flexible Weibull extension (EFWE) distribution which ...
