I ran a model to find whether there was evidence of an interaction or not between two variables. According to the credible intervals, there was evidence of just one out of three possible interactions. I ran the model again and now two out of three seem to have evidence in favour. How come an interaction can appear and dissapear? Here are the last results I have after running the model again.
( b = -0.19, SD = 0.47, CI = [-1.12, 0.75])
( b = -1.18, SD = 0.54, CI = [-2.21, -0.13])
( b = -1.37, SD = 0.53, CI = [-2.42, -0.35])
