For water quality classification, the analyses were carried
out using multivariate data analysis such as linear discriminant
analysis (LDA). This statistical method is usually applied for
data classification and dimensionality reduction. LDA seeks to
lessen dimensionality though preserving as much on the class
discriminatory details as possible [7]. LDA operate
instantaneously when the intra-class frequencies are unequal
and their performance has been examined on randomly
generated test data.
