'We must mitigate the climate problem...' You're what we call an educated idiot. There is a CO2 dearth at this time. NOT a 'climate change' induced by human activity. SMH

At 57:39 you say "make sure you are okay with setting the scale of that item". Lets say all items are measured on the same scale (likert 0 to 5). How do we assess whether we are okay with setting a particular item as the reference item? Spontaneously Im thinking that in the case of a likert scale where all items are on the same scale, we would atleast want to ensure that the item that is used as the reference item is an item where each answer option (0, 1, 2, 3, 4, 5) has been used "equally" often? For example, using an item where 4 was not chosen by a single respondent - seems like a bad item to use as a reference item? Is this at all true?

Thanks for the informative video. For time-varying Cox model (2:32:50), do we still need to check PH assumption for the time-varying covariate? Thanks!

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.

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).
