GENERALIZED ADDITIVE MIXED MODELS FOR SMALL AREA ESTIMATION
Bibliographic record
Abstract
Small Area Estimation (SAE) is a statistical technique to estimate parameters of sub-population containing small size of samples with adequate precision. This technique is very important to be developed due to the increasing needs of statistic for small domains, such as districts or villages. Some SAE techniques have been developed in Canada, USA, and UE based on real data. We adapted this technique to produce small area statistic in Indonesia based on national data collected by the Statistics Indonesia (Badan Pusat Statistik). We found that the linear model applied to auxiliary data produced estimates with low precision. In this paper we propose a class of generalized additive mixed model to improve the model of auxiliary data in small area estimation. Another method which can be used to obtain higher precision in small area estimation may be developed by linking some information in particular area with some other areas through appropriate model. This procedure is called indirect estimation. The procedure involves data from other domains. In other words, small area estimation model is borrowing strength from sample observation of related areas through auxiliary data (recent census and current administrative records) to increase effective sample size (Rao, 2003). In this paper we will discuss small area estimation through indirect method or estimation based models. One of the problems found in using this procedure is low precision of linear model for modeling of auxiliary data. In this paper we propose a class of generalized additive mixed model to improve the model of auxiliary data in small area estimation. This paper also presents application on small area estimation using poverty data from Susenas 2005 and Podes 2005 at Bogor District in West Java.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
