✦ Synopsis

analysis of fracture toughness test data should provide dist~butional parameter estimates for the population of toughness predictions for use in integrity assessments. Standard statistical techniques are available which provide such information where the appropriate distributional form is normal but not where a skewed distribution (e.g. Weibull) is applicable. A procedure to analyse data for a Weibull distribution fit has been derived and is discussed. In this approach it is important to use the correct type of regression analysis. The assumptions of the statistical model. on which the analysis of multispecimen toughness data is based, are considered in the light of possible mechanisms of ductile crack growth. The implications of these mechanisms for the choice of regression analysis are discussed, and an assessment of the regression model based on the analysis of residuals is given.

The generalized estimation equation (GEE) method, one of the generalized linear models for longitudinal data, has been used widely in medical research. However, the related sensitivity analysis problem has not been explored intensively. One of the possible reasons for this was due to the correlated
