Abstract

A system that incorporates teachings of the present disclosure may include, for example, determining a first linear model and a first log-linear model according to first explanatory variables and a first plurality of occupancy estimates, determining a second linear model and a second log-linear model according to second explanatory variables and a second plurality of occupancy estimates, evaluating, according to a location of a building, the first linear model, the first log-linear model, the second linear model, and the second log-linear model according to first values of the first explanatory variables and second values of the second explanatory variables, and combining results from the evaluating to generate a mixed occupancy estimate. Other embodiments are disclosed.
