Knowledge of evapotranspiration at various stages plant development allows irrigation management to be more efficiently carried out according the actual crop demand. There are a variety methods that can used determine reference evapotranspiration, and due high variability parameters influencing this phenomenon, it is common have studies compare different evaluate which one has greatest applicab...
The starting point of this paper is given by Priestley’s papers, where a theory of representation of distributive lattices is presented. The purpose of this paper is to develop a representation theory of fuzzy distributive lattices in the finite case. In this way, some results of Priestley’s papers are extended. In the main theorem, we show that the category of finite fuzzy Priestley space...
Loosely speaking, a stationary time series is one whose statistical properties remain constant over time, whereas the statistical properties of locally stationary (LS) time series change slowly over time. As a consequence, LS series can appear stationary when examined close up, but appear nonstationary when examined on a larger scale. Priestley (1983) and Nason and von Sachs (1999) review local...
Three common classes of kernel regression estimators are considered: the Nadaraya–Watson (NW) estimator, Priestley–Chao (PC) and Gasser–Müller (GM) estimator. It is shown that (i) GM estimator has a certain monotonicity preservation property for any K, (ii) NW this if only K log concave, (iii) PC does not have K. Other related properties these discussed.
