This limitation may be viewed as resulting from an essential lack of information in the measurements about the unknown source function, which is codified in the concept of the null space of functions associated with the measurement geometry.

With regard to the latter task, we describe methods for learning both the parameters and structure of a Bayesian network, including techniques for learning with incomplete data. << for parameters that are not identified by the data.

Daniels Major: Statistics We consider inference in randomized longitudinal studies with missing data that is generated by skipped clinic visits and loss to follow-up. We developed a Bayesian nowcasting approach that explicitly accounts for reporting delays and secular changes in case ascertainment to generate real-time estimates of COVID-19 epidemiology on the basis of reported cases and deaths. Our approach is unique in that it evolves both the solution space of network structures and the values of the missing data.
