Analysis of cultivar by environment (C E) interaction can improve efficiency of crop breeding efforts. Variety selection and recommendation based on wheat (Triticum aestivum L.) yield testing trials could possibly benefit from this type of analysis as well. The objectives of the present work were to evaluate methods to identify relevant testing environments and improve the predictive value of d...

For more than 20 years, variants of correspondence analysis have arisen that accommodate for the structure ordered categorical variables using orthogonal polynomials. When visual display from this is biplot, projections linking origin to standard coordinate each category a common feature. In case when column variable, say, consists categories, biplot can be constructed so their determined polyn...

Kebutuhan jagung nasional cenderung mengalami peningkatan setiap tahunnya seiring semakin menurunnya luas lahan pertanian. Tumpang sari dapat menjadi solusi untuk meningkatkan produksi dalam efisiensi penggunaan pertanian yang berkurang. Varietas toleran tumpang dihasilkan melalui plasma nutfah memiliki variabilitas dan heritabilitas tinggi. Tujuan penelitian ini mengetahui informasi mengenai p...

This paper suggests a new methodology capable of accessing in detail the contribution of companies to countries’ sustainability related to economic performance. The concept of sustainability has been brought up in several debates, leading to a clearer understanding of its progress in recent decades. The most adequate indicators to achieve a unique value to define sustainability have been identi...

The presented considerations complement our former paper (B&Asz) entitled “The augmented biplot and some examples of its use” (Machine Graphics and Vision, 4, 1995, 161–185). Now we consider some topics concerned with a 3D representation of n points–individuals and p points– variables included in a data matrix Xn×p. The representation is displayed in the form of a spinplot called also spinner. ...
