Naturally, there's some error in that kind of estimation process.

Uncertainty was propagated throughout the demographic estimation process, including fertility, mortality, and population, with 1000 draw-level estimates produced for each metric.

Moreover, we demonstrate that the XSlit camera exhibits ambiguities in pose estimation process which can not be handled by existing work.

The authors validated the estimation process with digital lesion phantoms that simulated varying levels of segmentation error and missing surface information.

Although methods have also been derived for countries with low level or concentrated epidemics, more data on the biases in the estimation process are required.
