Web2 de mar. de 2024 · Overlapping curves with near-zero slopes suggests no interactions. If I modify the data to add an interaction between the two continuous variables the result is overlapping and close-to-parallel lines with non-zero slopes. That is, the interaction of these two variables has an effect, but it's not very different for each of the categorical ... WebStudy sites are included as the random effect in the model (with the random slope and random intercept). Landuse, species (and their interaction) are included as fixed effects. the model is this -. model1 = lmer (carbon ~ species*landuse + (1+landuse site), data) I know that there may be interaction between landuse and species. WebHere, we need the Law of Cosines. a and b are pointing partially in the same direction. We switch to interaction mode to get to a common, combinable unit (area): a 2 = 100 b 2 = 400 2 a b = 2 ⋅ 10 ⋅ 20 = 400, but we need to adjust by the interaction factor. That is cos ( 45) = .707, so the real interaction factor is 400 ⋅ .707 = 282.8 how to scroll up in terminal
