Estimating a Structural Distribution Function by Grouping
The concept of a structural distribution function originates from linguistics. Let M denote the size of the vocabulary of an author and consider a text of this author that contains n words. Every choice of a word in the text from the vocabulary can be seen as the realization of a multinomial random vector. The whole text consists of a sequence of such choices X = (X (i) 1,M , . . . , X (i) M,M)...
متن کاملEstimating a Distribution Function for Censored Time Series Data
Consider a long term study, where a series of dependent and possibly censored failure times is observed. Suppose that the failure times have a common marginal distribution function, but they exhibit a mode of time series structure such as-mixing. The inferences on the marginal distribution function are of our interest. The main results of this paper show that under some regularity conditions, t...
متن کاملestimating the wind erosion climatic factor using regional distribution function
wind erosion climatic factor is a measure of climatic factors explaining the wind erosion erosivity. humidity and wind speed are climatic characteristics that must be considered as the erosion parameters. in this study, linear moment analysis (l-moments) and wind erosion climatic factor were used to evaluate the regional climate’s tendency effect on wind erosion in yazd province. wind erosion c...
متن کاملEstimating a Bounded Normal Mean Under the LINEX Loss Function
Let X be a random variable from a normal distribution with unknown mean θ and known variance σ2. In many practical situations, θ is known in advance to lie in an interval, say [−m,m], for some m > 0. As the usual estimator of θ, i.e., X under the LINEX loss function is inadmissible, finding some competitors for X becomes worthwhile. The only study in the literature considered the problem of min...
متن کاملEstimating the Structural Distribution Function of Cell Probabilities
Abstract: We consider estimation of the structural distribution function of the cell probabilities of a multinomial sample in situations where the number of cells is large. We review the performance of the natural estimator, an estimator based on grouping of the cells, and a kernel type estimator. Inconsistency of the natural estimator and weak consistency of the other two estimators is derived...
