Most countries with indications models permit much broader rationales than Romney proposes -- 36 countries allow abortion to preserve a woman's physical health, 23 countries add preservation of mental health as an acceptable indication, and another 14 only require that women offer a socioeconomic reason.
The following models were generated: unadjusted; age-adjusted; adjusted for demographics, risk factors for HS, and enrolment status in the HT, dietary modification and extension study (model 1); adjusted for variables included in model 1 plus variables that may lead to confounding by indication (model 2).
Risk of HS by statin use (time-varying covariate, with the 'no use' category as the referent) was estimated from Cox proportional hazard regression models adjusted for age (model 1); risk factors for HS (model 2); and possible confounders by indication (model 3).
Within each of the four item sets (i.e., cognitive impact, emotional impact, physical impact, and social functioning impact), we conducted confirmatory factor analysis (CFA) using structural equation modeling (SEM) and followed common current practice with regard to indications of model fit [ 39, 40].
We relied on the Comparative Fit Index (CFI), Tucker-Lewis Index (TLI) and root mean square error of approximation (RMSEA) as indications of model quality.
It was demonstrated that such approaches can lead to early indications of model predictions, and intuitively demonstrate these in a biological manner.
The comparisons of observed data to the Tohoku 2011 and Chile 1960 modelled events are therefore not equivalent and the Tohoku 2011 comparison may be the more reliable indication of model uncertainty at the Fort Denison tide gauge.
The standard error of the individual neural network predictions is taken as the indication of model prediction reliability and is incorporated in the optimization objective function.
