Second, the study shows that estimators
using only one prior year of data are substantially less accurate than estimators
using two or three years of prior data, particularly for smaller hospitals.
In order to carry out the comparison between the estimators
, we need to know the a priori SNR [[xi].
Six non-parametric estimators
were calculated: four incidence estimators
(Jacknife 1, Jacknife 2, Chao2 and Incidence-based Coverage Estimator
) and two abundance estimators
(Abundance-based Coverage Estimator
are used in this experiment; they are Ordinary Least Squares (OLS), Two Stage Least Squares (2SLS), Limited Information Maximum Likelihood (LIML), Three Stage Least Squares (3SLS) and Full Information Maximum Likelihood (FIML).
The main objectives of the present study were: a) describe several lag-one autocorrelation estimators
, presenting the expressions for their calculus; b) propose a new estimator
and test it in comparison with the previously developed estimators
in terms of bias and Mean Square Error (hereinafter, MSE); c) estimate the statistical power of the tests associated with the ten estimators
and based on Monte Carlo sampling.
The three-year enterprise agreement covers the entire suite of DESTINI estimating products, including 30 Estimator
licenses and 10 Profiler licenses.
In this section we have presented details of the data-aided (DA), non-data-aided (NDA) and partially data-aided (PDA) ML estimators
Proposed Ratio Estimators
for Population Variance in Adaptive Cluster Sampling: Following (Isaki, 1983) the proposed ratio type variance estimatorin ACS:
Using the known knowledge of the auxiliary variables Kadilar and Cingi , suggested the following class of ratio estimators
for population mean of the variable under study under simple random sampling (Eq.
North America is the largest market for power system state estimators
, while Latin America is the one with the highest projected CAGR.
can also provide improved decision support with a better understanding of group dynamics.
It can be noted that although both estimators
are very close to the theoretical one, the K phase estimator
seems to have an error smaller than the K power estimator
