    Great explanation. Has anyone ever thought of using these ideas for a language model? It could have continuous learning built in, due to the Bayesian Approach.

    General comment Prof. , @9.07, the real part id the natural frequency and wi is the growth rate of the eigenvalue problem. Thats the general convention.

    The first half was really great as an introduction to the topic. The second half is absolutely useless. Filling your slides with formulas and switching back and forth between slides is no way to teach a topic.

    Thank you for such a detailed introduction to SEM. I have a question - at 46:18 the model is called a "saturated model" because the df = 0. However I have been reading that a "saturated model" occurs when there are the same number of parameters as there are data points. In this case, the model has 5 parameters and 500 data points. Is it still a saturated model then?

    great video! Thanks. What do you think of using the estimation method DWLS instead of ML for ordinal items (such as those in the video "strongly disagree to strongly agree")? I have just read a paper (Reimann et al. 2024) where they used DWLS in a 2-factor CFA and got a great RMSEA (0.01). Their rationale was that the responses are ordinal and not continuous. Interestingly, I could run the same data set with ML and got an RMSEA = 0.13. Obviously a big difference. In papers, authors often do not even mention their estimation method.

    I am in an intermediate statistics and research course for my doctoral program. I began reading Hayes and found myself dissociating with glazed stares. This workshop has provided an informative path to at least begin to consume the material with some understanding. Your assistance with downloading the PROCESS macro was also very helpful. I hope to find moderation and conditional process analysis workshops from this source as well. Thank you very much!!

    Thank you very much for an excellent lecture on CFA. Just a small comment/correction on the very final exercise: the Test statistic for the User Model, is 554.191. In your solution, it is 562.790. and the Degree of Freedom is 20, not 21. By putting these numbers in the formula, we get the correct CFI, which is 0.871 (rounded).

    The HR for wt.loss in the lung data has a p value in excess of 0.05. Thus it is not statistically significant.

    I am not really seeing the difference between informative and formative censoring. I am also struggling with the comparison with NAs. NAs missing at random is easy to spot but not so sure about the censoring.

    This is a very informative presentation and clearly laid out. However, in terms of earthquakes I don't think it is safe to say that the hazard is constant. Hazard along the San Andreas fault should clearly vary depending on the region next to the fault (rock types vary, last time there was earthquake and so on).
