Taguchi has introduced the loss function approach to quality improvement by focusing on the reduction of variation around the target value. This concept pays attention to the product designer's original intent; that is, values of a critical characteristic at a target lead to maximum product...

Estimated associations between an outcome variable and misclassified covariates tend to be biased when the methods of estimation that ignore the classification error are applied. Available methods to account for misclassification often require the use of a validation sample (i.e. a gold...

As an alternative to the classical approach for analysing dichotomous choice environmental valuation data, this note develops a Bayesian approach by using the idea of Gibbs sampling and data augmentation. A by-product from the approach is a welfare measure, such as the mean willingness to pay,...

In this paper, we present a Bayesian methodology for modelling accelerated lifetime tests under a stress response relationship with a threshold stress. Both Laplace and MCMC methods are considered. The methodology is described in detail for the case when an exponential distribution is assumed to...

Capability indices that qualify process potential and process performance are practical tools for successful quality improvement activities and quality program implementation. Most existing methods to assess process capability were derived on the basis of the traditional frequentist point of...
