Webdfr. ## [1] 88. Now we have one vector of estimates to be compared and one vector of standard errors. In this situation, we can make pairwise comparisons by using the. pairComp() function in the ‘aomisc’ package. We just have to pass the vector of model parameters, the vector of standard errors, and, optionally, the names of parameters (we ... WebMost recent answer. 25th Aug, 2024. Lucas Loerch.

WebAll pairwise comparisons. One way to use emmeans(), which I use a lot, is to use formula coding for the comparisons.This formula is defined in the specs argument.. I will do all pairwise comparisons for all combinations of f1 and f2.The built-in function pairwise is put on the left-hand side of the formula in specs and the factors with levels we want to compare … WebCumulative link models are a different approach to analyzing ordinal data. Models can be chosen to handle simple or more complex designs. This approach is very flexible and might be considered the best approach for data with ordinal dependent variables in many cases. However, a few disadvantages to using these models are that 1) your audience ...
