Hi all, Our next virtual meeting will be at 12pm (EST) Wednesday, November 18, where we will hear Tyler VanderWeele (Harvard University) presents research on "Revisiting Psychometric Theory and Factor Analysis." *Abstract*: The presentation will revisit some of the conceptual and statistical foundations of psychometric measurement theory and factor analysis, specifically addressing the questions: (i) What happens to “factors” when they causally affect one another?, (ii) Is an underlying univariate latent variable a reasonable model for psycho-social constructs?, (iii) What are the testable empirical implications of such a model? and (iv) What alternative interpretations of analyses with constructed measures might be possible? The presentation will be based upon the following three preprints: - VanderWeele, T.J. and Batty, C.J.K. (2020). On the dimensional indeterminacy of one-wave factor analysis under causal effects. <https://arxiv.org/abs/2001.10352> Technical Report. - VanderWeele, T.J. and Vansteelandt, S. (2020). A statistical test to reject the structural interpretation of a latent factor model <https://arxiv.org/abs/2006.15899>. Technical Report. - VanderWeele, T.J. (2020).
