Non-Linear Visualization and Importance Ratio Analysis of Multivariate Polynomial Regression Ecological Models Based on River Hydromorphology and Water Quality

Abstract: Multivariate polynomial regression (MPR) models were developed for five macrophyte indices. MPR models are able to capture complex interactions in the data while being tractable and transparent for further analysis. The performance of the MPR modeling approach was compared to previous work using artificial neural networks. The data were obtained from hydromorphologically modified Polish rivers with a widely varying water quality. The modeled indices were the Macrophyte Index for Rivers (MIR), the Macrophyte Bi… Show more

“…According to the results of the multiple linear regression, 31 it was necessary to analyse the possible nonlinear relationship including an interaction effect between the reaction conditions. 32 Since the units of temperature, Co loading, Co/SiO 2 , HAP, and ethanol added per minute differ (Table 8), the data for these variables were divided by the corresponding data in the rst row in order to remove the units. From previous analyses, multiple interaction effects are known to exist under charging method I, and multiple nonlinear regression was used.…”
