Bayesian confirmatory analysis of multiple response data

Applied Marketing Analytics: The Peer-Reviewed Journal, 2017
This paper proposes a Bayesian confirmatory factor-analytic probit model to reveal the latent utility structure of multiple response data commonly found in marketing surveys. It conditions model formulation on previous knowledge and imposes a parsimonious hierarchical structure involving a measurement model (to define common factors) and a structural ...

Descriptive Data Analysis: A Concept between Confirmatory and Exploratory Data Analysis

Methods of Information in Medicine, 1987
SummaryConfirmatory Data Analysis (CDA) in randomized comparative (“controlled”) studies with many variables and/or time points of interest finds its limitations in the multiplicity of desired inferential statements which leads to unfeasibly small adjusted significance levels (“Bon-ferronization”) and, thereby, to unduly increased risks of not ...

Data-Driven and Confirmatory Subgroup Analysis in Clinical Trials

2020
In 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 ...

Quantified Neurophysiology with mapping: Statistical inference, Exploratory and Confirmatory data analysis

Brain Topography, 1990
Topographic mapping of brain electrical activity has become a commonly used method in the clinical as well as research laboratory. To enhance analytic power and accuracy, mapping applications often involve statistical paradigms for the detection of abnormality or difference.

Pairwise stochastic approximation for confirmatory factor analysis of categorical data

British Journal of Mathematical and Statistical Psychology
Abstract Pairwise likelihood is a limited‐information method widely used to estimate latent variable models, including factor analysis of categorical data. It can often avoid evaluating high‐dimensional integrals and, thus, is computationally more efficient than relying on the full likelihood.

Main Study—Data Reduction and Confirmatory Factor Analysis

2017
The main research study consists of obtaining feedback through the questionnaire developed from all the organizations identified for data collection. In this context, a sample size of 270 organizations was considered for the main study. Out of 270 samples, 150 are from Bangalore region (Karnataka) and remaining 120 from Coimbatore region (Tamil Nadu ...

Incorporating external real-world data (RWD) in confirmatory adaptive design

Journal of Biopharmaceutical Statistics
Adaptive designs, such as group sequential designs (and the ones with additional adaptive features) or adaptive platform trials, have been quintessential efficient design strategies in trials of unmet medical needs, especially for generating evidence from global regions.
