Small Area Estimation under Spatial Multivariate Fay--Herriot Model
hukum chandra, Saurav Guha. Not indexed, 2021-02-17
Topic: Risk, prevention and care in population studies
Spatial version of multivariate Fay–Herriot model is introduced and small area predictor under this model is proposed. The mean squared error (MSE) estimation of the proposed small area predictor is also developed. The empirical performance of the proposed small area predictor and the MSE estimator are evaluated through simulation studies. The empirical results clearly show that the proposed small area predictor outperforms the existing predictors. The proposed MSE estimator tracks the actual value of MSE reasonably well with acceptable coverage rate. An application to estimate the disparities in food and nutrition intake from the 2011–12 Household Consumer Expenditure Survey data collected by the national sample survey office of India is also presented.
Key findings
- The empirical results clearly show that the proposed small area predictor outperforms the existing predictors.
Why it matters
This study is about a statistical model for small area estimation, not Alzheimer's disease, so it does not provide information on treating, curing or preventing Alzheimer's. It found that the proposed predictor performed better than existing predictors in simulations.

How this study scored 28/100
Published in a peer-reviewed journal. Scored zero for study design, sample size, effect reported, studied in people and randomised / blinded because the record does not state it. We have no data on journal's citation record, impact for its field and year and institution's track record, so those were left out: it earned 24 of the 87 points we could judge it on, which is 28 out of 100.
