First thing that came to mind is: can this model correlation between each cell, or does it assume that all cells are independent?

For example, in this https://www.getguesstimate.com/models/2205 hours of sleep per night is perhaps correlated with hours per weekday commuting. You might not have the data, but if you do, it could improve the probability distribution in the "weekday hours occupied" cell
