Moreover, estimates produced from repeat pass LiDAR datasets were consistent and highly correlated (R2 0.98) suggesting that the approach is precise and robust, provided that key tillage parameters (i.e. presence of vegetative material and row direction) can be pre-classified.
Validation results suggest strong agreement between the estimates produced from the forest inventory plots and those from the imputed maps, particularly when the C pool is closely associated with the imputation model (e.g., aboveground live biomass and live tree basal area), with weaker agreement for detrital pools (e.g., standing dead trees).
The estimates produced from these data indicate that the number of new infections rose rapidly during the early 1990s, peaking in the mid-1990s befallinglling to a stable level of about 18,000 new infections per year today.
The seroprevalence estimates produced from each test were significantly different in both males (P < 0.001) and females (P < 0.001).
Indeed, the estimates from a GEE analysis can sometimes be smaller than those estimates produced from a corresponding mixed-effect model (12).
To sort out differences between estimates produced from different sources using different methods, UNICEF developed, in coordination with WHO, UNDP and the World Bank, a method that minimizes the errors embodied in each estimate and harmonizes trends along time [ 22].
Two strategies for model building, S1 and S2, were explored – both utilizing a single imputed data set generated from the ML parameter estimates produced from the EM algorithm for covariance matrices.
There is also evidence from prior methodological work that CACE estimates produced from latent class modelling are insensitive to the missing data assumption used, missing at random or latent ignorability [ 24].
Inadequate sample size contributed to an insufficient number of observations in the risk groups of the initial selection of explanatory variables and this may bias the risk estimates produced from such a model.
