WebWe would like to show you a description here but the site won’t allow us. WebThe trick to doing EFA within a CFA framework is to use the same number of constraints in CFA as are used in EFA. If m is the number of factors in an EFA model then the number of constraints is m2. By using m2 constraints in CFA we get a model with the same fit as an EFA model. We will demonstrate EFA within a CFA framework using an artificial ...

WebEFA/CFA could be similar/dissimilar depending on methodology 2. Orthogonal rotation is often used in the context of EFA, making the factors uncorrelated with each other. 3.
