This paper discusses a formulation of new environmental quality indices, which
can be used for monitoring environmental as well as meteorological parameters.
The formulation of the indices is based on conventional and robust principal
component analysis, which gives the linear combination of environmental
parameters. Comparisons are made between the conventional principal
component analysis (PCA) indices and robust principal component analysis
(RPCA) indices. The results show that the RPCA gave a better alternative linear
combination. A numerical example on air quality was used to illustrate the
application of the robust environmental indices. |
