BI-HYPERIDEALS AND QUASI-HYPERIDEALS IN ORDERED SEMIHYPERGROUPS
, 2015 In this paper, we introduce concepts of bi-hyperideals and quasi-hyperideals of an ordered semihypergroup and present several examples of them. Some properties and relationships between bi-hyperideals and quasi-hyperideals are investigated.

Some properties of quasi-gamma-hyperideals and hyperfilters in ordered gamma-semihypergroups
, 2018 WOS:000429448200007In this paper, we give some characterizations of the regularity of an ordered Gamma-semihypergroup in terms of left, right and quasi-Gamma-hyperideals. Also, we define and use the notion of hyperfilters in ordered Gamma-semihypergroups

Estimating ordered categorical variables using panel data: a generalized ordered probit model with an autofit procedure [PDF]
Estimation procedures for ordered categories usually assume that the estimated coefficients of independent variables do not vary between the categories (parallel-lines assumption).

On intra-regular ordered semigroups
, 1998 The intra-regular ordered semigroups are semilattices of simple semigroups. The decomposition of intra-regular ordered semigroups with or without a greatest element into their simple subsemigroups, in general, is not uniquely defined.

PROPERTIES OF HYPERIDEALS IN ORDERED SEMIHYPERGROUPS
, 2014 An ordered semihypergroup is a semihypergroup (S; ∘) together with a partial order ≤ on S such that the monotone condition holds, i.e., for all x, y, a ∈ S, if x ≤ y, then for all u ∈ x ∘ a there exists v ∈ y ∘ a such that u ≤ v, and similarly, for

Left Regular Ordered AG-Groupoids
, 2020 In this article, we extend the notions of left(right) ideal, left(right) ideal element to the left(right)simple ordered AG-groupoids, left(right) regular ordered AG-groupoids, and regular ordered AG-groupoid. Wepresent the main results which characterize

On left regular and intra-regular ordered semigroups
, 2014 We study the decomposition of left regular ordered semigroups into left regular components and the decomposition of intra-regular ordered semigroups into simple or intra-regular components, adding some additional information to the results considered in [

We discuss regression models for ordered responses, such as ratings of bonds, schooling attainment, or measures of subjective well-being. Commonly used models in this context are the ordered logit and ordered probit regression models.
