For binomial data and logistic regression, the effectiveness of these designs for screening is assessed through simulation studies using all-subsets regression and model selection via maximum penalised likelihood and a generalised information criterion.
A generalised Drucker Prager yield criterion, that includes the gradient influence on the deviatoric stress, is proposed and then employed to investigate the collapse loads for soil layers under conditions of generalised plane-strain, simple shear and uniaxial compression.
The smoothing parameter λ ∈ [0, ∞) is estimated by optimising a generalised cross-validation criterion. For more detail, see publications by Ramsay et al [ 17, 18].
Thin-plate regression splines were used as trend smoothers, as proposed by Wood [ 27], and the optimal degrees of freedom were automatically selected using a generalised cross-validation criterion [ 28].
Therefore, previous work has only provided generalised gas screening criteria and a more detailed screening of each of the methods would be needed for successful implementation.
The generalised cross-validation criteria were used to fit the best model.
The seven-item Primary Care Evaluation of Mental Disorders Patient Health Questionnaire (PRIME-MD PHQ) anxiety scale assesses symptoms consistent with DSM-IV diagnostic criteria for generalised anxiety disorder (Spitzer et al, 1999).
The scale has good psychometric properties and successfully discriminates between individuals with all, some, or none of the diagnostic criteria for generalised anxiety disorder (Meyer et al., 1990).
Women are twice as likely to meet the criteria for generalised anxiety disorder as men, 29 and gender differences in prevalence of general anxiety disorder usually emerge in early adolescence.
Based on the classification and Uniaxial Compressive Strength test results, rock mass strength was defined using generalised Hoek-Brown's failure criteria.
