Two probability model options are available: 

'Population Average' includes only population level (i.e. occupant type, age, employment) differentiation of the base Markov probability models. This model does not reflect the behaviour of individual households but the population average response over time.

The 'Individual' option includes additional within-population differentiation in relation to wake, sleep and daytime absence timing that are used to shift the Markov timing basis for individuals. The input from this model includes behaviour that is appropriate for individual households.

'Individual' models are most appropriate for investigations of the impact of different behaviours, while 'Population Average' models are most appropriate for general stock modelling and to determine typical responses.
