Threshold Exceedance Estimation in Spatially Correlated Areal Data Using Maxima-Nominated Sampling
Mohammad Jafari Jozani
We study estimation of the proportion of areal units in a spatially correlated domain whose success probabilities exceed a prespecified threshold. Such problems arise in health sur…
L-Estimation of Population Quantiles Using Ranked Set Sampling
Mohammad Jafari Jozani, Ehsan Zamanzade, Reza Modarre
Quantile estimation is central when interest lies in thresholds or tail behavior rather than the mean. When exact measurement is costly but units can be ranked cheaply, ranked set…
Elite-Driven Support Vector Machines for Classification
Mohammad Jafari Jozani, Bahram Moeinianfar
Support vector machines (SVMs) are a standard tool for binary classification, but their classical formulations are purely data-driven and offer no direct way to encode trusted benc…
Fractionally Supervised Classification with Maxima Nominated Samples
Mohammad Jafari Jozani, Jingyu Wang
Fractionally supervised classification (FSC) offers a flexible framework for combining labeled and unlabeled data in model-based classification, but existing formulations assume si…
