“…Given its dependence on one continuous random variable and one discrete random variable, the stationary joint density function, g (a, e), can be split into g (a, e h ) and g (a, e l ). Following Khieu and Wälde (2019), we refer to these individual probability functions as subdensities. For each e ∈ E, it follows that g (a, e) ≡ g (a | e) p (e), implying that g (a, e) da = p (e) ,…”
