Derived cluster profiles at an inter-dwelling electricity demand. (a) Elliptical shape and the coloured boundaries denote the Gaussian clusters with outliers derived in two-dimension; (b) Bayesian Information Criteria (BIC) plots for 14 models fitted to the electricity consumption data showing the geometric characteristics of this multidimensional data and its covariance parametrisation. [Note: In one dimension, there are just two models: E for equal variance and V for varying variance. In the multivariate setting, the volume, shape, and orientation of the covariances can be constrained to be equal or variable across groups that result in 14 models (see Appendix: Fig A1 and Table A3).].
