Data Preparation and Univariate Aspects

The elements Co, Mo, and Sb were excluded from the determined 27 features (26 elements and total sedimented particulates) because their values were below the detection limits. The relative frequencies of the four main wind directions at the sampling point

3 Combination of Cluster Analysis, and Multivariate Analysis of Variance and Discriminant Analysis 

Results from hierarchical agglomerative cluster analysis according to the algorithm of WARD (see Section 5.3) are illustrated as a dendrogram in Fig. 7-14. Distinction of the months in which the heating of buildings has a large influence from the summer months is clearly demonstrated. November and December of the second year of the in-
