Confirmatory Factor Analysis of Ordinal Data Using Full‐Information Adaptive Quadrature
Australian & New Zealand Journal of Statistics, 2016SummaryWe conducted confirmatory factor analysis (CFA) of responses (N=803) to a self‐reported measure of optimism, using full‐information estimation via adaptive quadrature (AQ), an alternative estimation method for ordinal data. We evaluated AQ results in terms of the number of iterations required to achieve convergence, model fit, parameter ...

Data-Driven and Confirmatory Subgroup Analysis in Clinical Trials
2020In this chapter we provide an overview of the principles and practice of subgroup analysis in late-stage clinical trials. For convenience, we classify different subgroup analyses into two broad categories: data-driven and confirmatory. The two settings are different from each other primarily by the scope and extent of pre-specification of patient ...

Mining medical claims data with exploratory to confirmatory statistical methods
International Journal of Public Policy, 2012Medical billing errors constitute a major problem in the medical payment system in the USA. Little is known about how to identify the predictors that influence the error rate in hospital billings. Health services researchers have concentrated to a large extent on applying exploratory statistical methods to identify the patterns of care and analyse the ...
