Here I take DemocracyIncome as an example. I need to simulate this dataset but I don't know which probability distribution of democracy and income I should choose. The dataset can be obtained from the following codes
library(pder)
data("DemocracyIncome", package = "pder")
Can anyone help me with the distribution of income and democracy? How can I simulate this democracy? I did a densityplot also and found that democracy has two to three peaks. It seems like a bimodal distribution.
