Since the OBCOST software does not work when one or more cells are incomplete, estimations were made for missing data.
In fact concerning the first one, there would be no hope to perform incomplete data estimation if no complete data estimator exists, whereas the second requirement consists only in being able to simulate random values according to the a posteriori law.
In [7], Bhattacharya and Başar have adapted compressive sensing techniques to state estimation under incomplete measurements.
Although our analysis presents a new perspective on the phylogeny and evolution of tetraodontid pufferfishes, we cannot rule out the possibility that this incomplete taxonomic sampling causes estimation errors on phylogeny and divergence times of freshwater species.
Total cost estimation from incomplete data collection in the case of two data collections was significantly lower independent of whether extrapolation (3.9%) or interpolation (4.6%) was used.
Since proxy-reporting relates to the number of meals under parental control, inaccurate estimation and incomplete reports of food and beverage consumption may also contribute toward reporting bias [ 47].
On the other hand, because of limiting experimental facility, the measured data for parameter estimation are incomplete; in particular, in many cases only a part of the variables in the model can be measured.
We analyze the impact of incomplete annotations on accuracy estimation using two confusion matrices, one provided at the time of original evaluation and the other at a later point in time when additional experimental annotations become available (Fig. 1).
The approach also makes it possible to make estimations under incomplete information.
Another limitation of this study is the reliance on expenditure data, which may be weakened by over- and under-estimation and incomplete recording and do not reflect the whole economic cost.
