Epidemiology and public health research relating to solar ultraviolet (UV) exposure usually relies on dosimetry measure UV doses received by individuals. However, measurement errors affect each unknown amounts, complicating the analysis of such measurements their relationship underlying population associated outcomes. This paper presents a new approach estimate without use dosimeters. By combin...

We develop a novel approach to estimating the integrated variance of a general jump-diffusion with stochastic volatility. Our approach exploits the relationship between the speed (distance traveled per fixed time unit) and passage time (time taken to travel a fixed distance) of the Brownian motion. The new class of duration-based IV estimators derived in this paper is shown to be robust to both...

Abstract Cardinality estimation is a fundamental task in database query processing and optimization. As shown recent papers, machine learning (ML)-based approaches may deliver more accurate cardinality estimations than traditional approaches. However, lot of training queries have to be executed during the model phase learn data-dependent ML making it very time-consuming. Many those or example u...

Establishing satisfactory estimation methods of lake evaporation has been crucial vital for research and management of water resources and ecosystems. Determining the accurate method to estimate evaporation from reservoirs in the investigation and management of water resources is very important. Hence, in this study eight empirical methods such as; Makkink, DeBruin-Kejiman, Penman, Priestley-Ta...

Abstract. Maximum likelihood (ML) estimation based on bivariate record data is considered as the general inference problem. Assume that the process of observing k records is repeated m times, independently. The asymptotic properties including consistency and asymptotic normality of the Maximum Likelihood (ML) estimates of parameters of the underlying distribution is then established, when m is ...
