Retraction Note: Evolution of rainfall runoff relationship based on nonparametric model and movement recognition of aerobics training

Abstract

From the perspective of nonparametric model, this paper focuses on nonparametric model and its application research; integrates nonparametric regression model, autoregressive nonparametric model, nonparametric VAR model family, nonparametric panel time series model, and height model estimation methods; and summarizes the application and development prospects in the case of analyzing time series. Based on this, this paper investigates the impact of the evolution of four rainfall runoff relationships on the main roads and residential areas in the middle of C City. By analyzing the 30–40% pollution load of runoff to the main road and residential area, it shows that the initial scouring effect of surface runoff in C City area is obvious. At last, this paper defines the movement recognition standard of aerobics training of students in G Province, and the results of the two groups are improved, and the test results of the experimental group are better than those of the control group, showing obvious causal differences. Eight indexes related to the experiment were analyzed. The average scores of the experimental group were higher than those of the control group in accuracy, range of motion, speed, body coordination, movement and music coordination, movement tension, and beauty, and there were significant differences between them; the average performance of the experimental group was higher than that of the control group, but the difference was not significant. The control group performed better than before in all aspects of the evaluation, but there was no significant difference in the eight indicators. To sum up, the experimental results show that the subjects’ sense of rhythm enhancement is a key optimization factor of aerobics training.
