Use of mathematical methods in the analysis and forecasting of nitrogen-phosphorus cycle indicators in the Pregolya river basin
... temporal dynamics. To analyze data on indicators of the nitrogen and phosphorus cycles, methods of multivariate statistics were applied, including hierarchical cluster analysis (Ward’s method), factor analysis (minimum residual method with varimax rotation), and time-series analysis (LOESS smoothing). As a result of the cluster analysis, three groups of observations were identified, reflecting different periods of nutrient input. Factor analysis made it possible to identify two latent factors: ...
