AIM For the purpose of cost modeling, the semi-parametric single-index two-part model was utilized in the paper. Furthermore, as functional gastrointestinal diseases which are well-known as common causes of illness among the society people in terms of both the number of patients and prevalence in a specific time interval, this research estimated the average cost of functional gastrointestinal d...

the problem of hypothesis testing with a nuisance parameter is considered. two methods forusing fuzzy knowledge on the nuisance parameter to test hypotheses are suggested. these methods areneither a pure classical nor a pure bayesian approach to hypothesis testing, but rather related to both. afew known examples and their applications, which cannot be studied by the parametric statisticalmethod...

in this paper, we use parametric form of fuzzy number and we converta fuzzy linear system to two linear system in crisp case. conditions for the existence of a minimal solution to $mtimes n$ fuzzy linear equation systems are derived and a numerical procedure for calculating the minimal solution is designed. numerical examples are presented to illustrate the proposed method.

Combining (35) with (34), and the fact that 1nb = 0, we have that P(A,θ,π0) = P(Ã,θ,π0). Since à has identical (n−1)-th and n-th columns, and fθn−1 = fθn we have that P(Ã,θ,π0) = P(Ā,θ̄,π̄0). Thus H ′ = (Ā, θ̄, π̄) is an equivalent (n−1)-state HMM and H is not minimal, proving the claim. We prove (35) by induction on the sequence length k ≥ 2. First note that since δ = 0, by Lemma 1 we have that

It is relevant to extend the existing single-level scaling methods to twolevel designs. Examples are the scaling of teachers on the basis of their pupils’ responses, or scaling neighborhoods on the basis of responses by inhabitants. A non-parametric approach is convenient because it requires few assumptions and leads to easy calculations. This paper considers a two-level situation where the obj...

Survival curves for each group gives comparison at some arbitrary point(s) but it does not provide a comparison of the total survival experience of two groups. So some Non-parametric methods like log rank test, Cox-Mantel test are popular methods used for comparing the survival distribution and also these methods takes whole follow-up period. In this paper non-parametric methods are used for da...

In this paper, we proposed a semi-parametric single-index two-part regression model to weaken assumptions in parametric regression methods that were frequently used in the analysis of skewed data with additional zero values. The estimation procedure for the parameters of interest in the model was easily implemented. The proposed estimators were shown to be consistent and asymptotically normal. ...
