Maybe the answer I contributed to [this question in the CrossValidated forum](https://stats.stackexchange.com/questions/584191/problems-with-emmeans-if-re-adjustment-and-backtransformation-from-logit/584407#584407) will address some of these concerns -- or maybe not...

just looking in. I see that `emmeans` is used to obtain coefficients for `psem` models, and things look pretty straightforward for that use, assuming appropriate variables are used. The only...

FWIW, I traced the `summary()` call at a point just inside `emmeans()`, after `object` is converted to an `emmGrid` and `specs` is converted to character. The `emmeans()` function is called...

@maschmoeller If you still have this problem when you simplify the model, then please do so!!! That is, it would be really, really helpful to provide a reproducible example of...

Looking at the documentation, I worked out that for the case of k = 2 (2 groups), we have ``` 2 * t delta n --------- = ----- x sqrt(-----)...

Mattan, Hmmm. No reference, as what I wrote there is just my derivation from basic principles. But it seems curious because, obviously, the more groups there are, the more df....

It does make sense to consider a contrast other than a pairwise one, with the interpretation that *d* is that contrast expressed in SD units. However, I don't think either...

If you give somebody an effect size, then you are giving them something that is in SD units. That means it is vitally important to understand exactly what those units...

@bwiernik -- Easy to say, but seldom easy to do. The documentation for `eff_size()` says (among other things): > For models having a single random effect, such as those fitted...

### Important note In `DESCRIPTION`, be sure to put in the dependency `emmeans (>= 1.1.2)`. ### Testing the example I can't get the example to run on my system: ```...
