    Investigating the Impact of Anthropogenic and Natural Sources of Pollution on Quality of Water in Upper Indus Basin (UIB) by Using Multivariate Statistical Analysis by Mansoor A. Baluch, Hashim Nisar Hashmi

    Published 2019-01-01
    “…Water quality of the Indus River around the upper basin and the main river was evaluated with the help of statistical analysis. In order to analyze the similarities and dissimilarities for identifying the spatial variations in water quality of the Indus River and sources of contamination, multivariate statistical analysis, i.e., principle component analysis (PCA), cluster analysis, and descriptive analysis, was done. …”

    Evaluation of the Genetic Diversity and Agro-morphophysiological Traits of Bread Wheat Varieties under Postflowering Drought Stress Using Different Statistical Methods by Mehdi Kakaei, Seyed Iman Mirmazloum

    Published 2024-02-01
    “…Factor analysis based on principal component analysis of the control plants revealed that three factors accounted for 64.68% of the total changes, including the first factor (yield), the second factor (characteristics related to height) and the third factor (harvest index), whereas the same analysis of the stressed plants at the end of the season indicated that three factors were behind 70.361% of the changes (yield and greenness, traits related to height, and plant moisture content). Based on all statistical analyses, (both univariate and multivariate of 14 studied genotypes), three winter-type varieties (Pishgam, Zare, and Mehan) were found to have significantly better yield under the drought stress conditions.…”
