New Paper Alert! Jess and her colleagues have a paper in review about a particular statistical method that we see a lot in developmental science. Have you ever run a confirmatory factor analysis and then saved (or extracted) the factor scores, turning them into observed scores for use in another analysis? If you have more than one latent factor, the default method for extracting factor scores can have some unintended consequences on the correlations between those newly created observed variables. But also describes how you can correct it. The link to the paper gives you the code to do it yourself. This episode is a bit numbery and a bit technical, but we think relevant for developmental scientists! Note. Posted with apologies to our reading research friends. Jess did not come up with good examples of what comprises reading on the fly in this episode. I am well aware a good fonging is in order. I do know better. I am sorry.
