For example, simple synthetic estimators are based on implicit modeling. These estimators use models, either implicitly or explicitly, that connect the small areas through supplementary (e.g., census and administrative) data.
Therefore, alternative estimators that borrow strength from other related small areas have been proposed in the literature to improve the efficiency. The direct-survey estimators, based only on the data from a given small area (or small domain), are likely to yield unacceptably large standard errors because of small sample size in the domain. v181 i1-4.Small-area estimation has received considerable attention in recent years because of a growing demand for reliable small-area statistics. Automatic calibration of conceptual rainfall-runoff models: sensitivity to calibration data. The missing values in obs and sim are removed before the computation proceeds, and only those positions with non-missing values in obs and sim are considered in the computation Author(s) Obs and sim has to have the same length/dimension If sim and obs are matrixes, the returned value is a vector, with the mean squared error between each column of sim and obs. Mse = mean( (sim - obs)^2, na.rm = TRUE) Value When an 'NA' value is found at the i-th position in obs OR sim, the i-th value of obs AND sim are removed before the computation.įurther arguments passed to or from other methods.
