Fan and Yao (1998) proposed an efficient method to estimate the conditional variance of heteroskedastic regression models. Chen, Cheng, and Peng (2009) applied variance reduction techniques to the estimator of Fan and Yao (1998) and proposed a new estimator for conditional variance to account...

Understanding and modeling dependence structures for multivariate extreme values are of interest in a number of application areas. One of the well-known approaches is to investigate the Pickands dependence function. In the bivariate setting, there exist several estimators for estimating the...

Cryptococcal meningitis (CM) is one of the most common fungal meningitides with high misdiagnosis rates and mortality. Therefore, rapid, accurate, and early diagnosis of CM is essential for successful treatment. In the present study, cerebrospinal fluid (CSF) samples from 69 suspected CM...
