Detection of Anomalies in Water Networks by Functional Data Analysis

Figure 2

Simulated data with 2 outliers. Left-hand panel: functions are generated from the main model (gray) and the contamination model (black). Central panel: archetypoids are represented with (red) solid, (green) dashed, and (blue) dotted lines, respectively. Right-hand panel: ternary plot showing the coefficients. The vertices of the triangle represent each archetypoid.
