WebSep 12, 2024 · 3. The fundamental difference between estimated marginal means (EMMs) and ordinary marginal means of data (OMMs) is that OMMs summarize the data, while EMMs summarize a model. Thus, if you fit a different model to the data, the EMMs are potentially different. EMMs are not just one thing. To be a bit more precise, EMMs involve … The Poisson model is a popular model for recurrent event data, which models the number of recurrences the have occurred. Poisson regression assumes that the number of recurrences has a Poisson distribution with a fixed rate of recurrence over time. The logarithm of the expected number of recurrences is modeled by a linear combination of explanatory variables.
