In this paper we provide a computation algorithm to get global solution for the maximum rank correlation estimator using mixed integer programming (MIP) approach. We construct new constrained optimization problem by transforming all indicator functions into binary parameters be estimated and show that it is equivalent original problem. also consider an application of best subset prediction can ...

In the typology of coefficients correlation, we seem to miss such estimators correlation as rank–polyserial ( R RPS ) and rank–polychoric RPC correlation. This article discusses a set options RP , including both . A new coefficient JT gX based on Jonckheere–Terpstra test statistic is derived, it shown carry essence Such traditional Goodman–Kruskal gamma G Somers delta D dimension-corrected 2 ar...

In this paper we investigate properties of rank correlation coefficients that can be derived from right-invariant generalized metrics on the symmetric group. We prove some new inequalities between a number of generalized metrics, and we characterize the sample sizes for which several (right-invariant) rank correlation coefficients can equal zero. Using the Hausdorff generalized metric, we show ...

Different responses of plant genotypes to the change of environmental conditions have been the most important and challenging issue for plant breeders and agronomists for the selection of superior genotypes. Cumin is one of the most important medicinal and aromatic plants in Iran that are strongly affected by varying environmental conditions. This study was aimed to investigate E×SD interaction...
