Hi thanks for this video! I was wondering if I could ask for one small clarification. In the first part of the video, you show the mathematical proof that a model with 2 specific factor composed of 3 indicators is not identified. However, in the second part you show that the 2 specific factor with 4 indicators is just identified and then say you could show that the 3 indicator model is also just identified. Does that mean the 2 specific factor composed of 3 indicators model (shown in the first part) is identified if the two specific factors are correlated?
Hi. I talk about the identification of a three indicator factor model here ruclips.net/video/i5sadBN8-dI/видео.html. If you have two specific factors of three indicators each, they are identified even if the two specific factors were uncorrelated. I talk about the identification rules for factor models ruclips.net/video/5awoT4ynXv8/видео.html&pp=sAQA This is an older video that just talks about rules without proving them, but could be useful. Please let me know if this helps.
