            A Poisson glm uses a log link function, and by default the predict.glm method returns the predictions without applying the inverse link function. You either need to use type = "response" inside predict, which will call the inverse link function on the predictions to give you predictions in the same units as your input data, or equivalently, since the inverse link function is essentially just exp, you can exponentiate the results of predict.

            So you can do either:

            Given your new data, I think that the best course of action is to consider that these two measurements, y1 and y2, were taken in batches and so should be treated as such, i.e. coming from the same batch which may have some intra-variation. To model this intra-variation you can use a mixed model, with the batches variable as a random effect rather than a fixed effect.

            ggeffects giving different prediction results from lm extracted as parsnip model, despite same coefficients
            Asked 2021-Dec-12 at 06:55

            I have a question about predictions using ggeffects, which is giving me completely different results if I use a traditional lm fit or an extracted parsnip model fit (despite having the same coefficients). Here is an example...

            ANSWER

            Answered 2021-Dec-12 at 06:55

            You are getting different results because lmmod_simp and lm_fit_extracted are different models. While lm_fit has an interaction effect on steps, lm_fit_extracted has no idea about this interaction as it gets the data after the interaction calculation has been performed.

            It is generally not recommended to pull out models from a workflow object if you plan on using it for other things than diagnostics.

            I am not entirely sure what I am doing wrong/what to look up. My objective is to use ggpredict and ggplot to display the relationship between time and the proportion of years burnt. I'm guessing it is something to do with the time variable being log transformed?

            ANSWER

            Answered 2021-Dec-07 at 18:29

            Okay, so I've figured out the main problem here. In the documentation of the ggpredict() function there is an argument called back.transform that defaults to TRUE. This means that log-transformed data will be automatically transformed back to the original response scale. This is why if you examine the ggpredict object d, you will see that the time variable actually does go to over 8000 in that object. So because you did not flag back.transform=FALSE, but also specified time[exp], what happened was the function automatically exponentiated your values, and then you did it again.

            QUESTION

            How to run the predicted probabilities (or average marginal effects) for individuals fixed effects in panel data using R?
            Asked 2021-Oct-26 at 18:47

            These are three different ways to run an individual fixed effect method which gives more or less the same results (see below). My main question is how to get predictive probabilities or average marginal effects using the second model (model_plm) or the third model(model_felm). I know how to do it using the first model (model_lm) and show an example below using ggeffects, but that only works when i have a small sample.

            As i have over a million individual, my model only works using model_plm and model_felm. If i use model_lm, it takes a lot of time to run with one million individuals since they are controlled for in the model. I also get the following error: Error: vector memory exhausted (limit reached?). I checked many threads on StackOverflow to work around that error but nothing seems to solve it.

            I was wondering whether there is an efficient way to work around this issue. My main interest is to extract the predicted probabilities of the interaction residence*union. I usually extract predictive probabilities or average marginal effects using one of these packages: ggeffects,emmeans or margins.
