IntroductionAsian citrus psyllid (ACP, Diaphorina citri) is an important transmission vector of “Candidatus Liberibacter asiaticus” (CLas), the causal agent of Huanglongbing (HLB), the most destructive citrus disease in the world. As there are cu

Citrus tristeza virus (CTV) is efficiently transmitted in a semi-persistent manner by the brown citrus aphid (Toxoptera citricida (Kirkaldy)). Currently, the most sensitive method for detecting plant viruses in insect vectors is reverse-transcription

In this article, we propose a new distribution by mixing normal and Pareto distributions, and the new distribution provides an unusual hazard function. We model the mean and the variance with covariates for heterogeneity. Estimation of the parameters

In this paper, we consider an inference method for recurrent event data in which the primary exposure covariate is assessed only in a validation set, while as an auxiliary covariate for the main exposure is available for the full cohort. Additive rat

By using Lamperti's bijection between self-similar Markov processes and Levy processes, we prove finiteness of moments and asymptotic behavior of passage times for increasing self-similar Markov processes valued in (0, ∞). We also investigate the b

This paper deals with the analysis of proportional rate model for recurrent event data when covariates are subject to missing. The true covariate is measured only on a randomly chosen validation set, whereas auxiliary information is available for all

In this paper, we obtain a law of iterated logarithm, a Chung-type law of iterated logarithm, and a moderate deviation result of the maximum likelihood estimator (MLE) for the unknown regression parameter vector in a proportional hazards model with i

Right randomly censored data with incomplete information are frequently met in practice. Although much study about right randomly censored data has been seen in the proportional hazards model, relatively little is known about the inference of regress

Let \( \tilde W \) (t)(t ∈ R+N) be the d-dimensional N-parameter generalized Brownian sheet. We study the polar sets for \( \tilde W \) (t). It is proved that for any a ∈ Rd, P{\( \tilde W \) (t) = a, for some t ∈ R>N} = \( \left\{ {\begin{arra
