    Spatial assessment of air quality patterns in Malaysia using multivariate analysis
    (Elsevier, 2012) Doreena Dominick; Hafizan Juahir; Mohd Talib Latif; Sharifuddin M. Zain; Ahmad Zaharin Aris
    This study aims to investigate possible sources of air pollutants and the spatial patterns within the eight selected Malaysian air monitoring stations based on a two-year database (2008-2009). The multivariate analysis was applied on the dataset. It incorporated Hierarchical Agglomerative Cluster Analysis (HACA) to access the spatial patterns, Principal Component Analysis (PCA) to determine the major sources of the air pollution and Multiple Linear Regression (MLR) to assess the percentage contribution of each air pollutant.The HACA results grouped the eight monitoring stations into three different clusters, based on the characteristics of the air pollutants and meteorological parameters.
