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…
Parametric inference for proportional (reverse) hazard rate models with nomination sampling
Mohammad Nourmohammadi, Mohammad Jafari Jozani, Brad Johnson
\noindent Randomized nomination sampling (RNS) is a rank-based sampling technique which has been shown to be effective in several nonparametric studies involving environmental and…
Exponentially Titled Empirical Distribution Function for Ranked Set Samples
Saeid Amiri, Mohammad Jafari Jozani, Reza Modarres
We study nonparametric estimation of the distribution function (DF) of a continuous random variable based on a ranked set sampling design using the exponentially tilted (ET) empiri…
