How Isolde works on a project

Isolde takes the advanced modelling briefs: structural equation models, confirmatory factor analysis, and the scale validation work that goes beyond a Cronbach's alpha. Doctoral committees that ask for measurement models are usually the reason she joins a project.

She works iteratively, sharing model fit and modification decisions as they are made rather than presenting a finished black box, so the student can defend every path in the final model.

The fastest way to work together is through our doctoral statistics support, which matches the projects this profile describes.
