Abstract
Due to the major consequences of air pollution on human health, this problem is resulting in a major public crisis which requires immediate attention. Nowadays, the prediction of air quality has been a potential research area. There exist a number of methods in literature, but the focus of this work is based on the prediction of air quality using time series analysis. This analysis has been carried out using univariate and multivariate techniques namely Autoregressive Integrated Moving Average (ARIMA) and Vector Autoregression (VAR) models. To perform the experimental work, the dataset of Gurugram has been considered. Further, the performance of both the models has been evaluated based on a number of metrics and it has been observed that the ARIMA model produced better results in comparison to VAR model for the prediction of Air Quality Index (AQI).
