Sparse Functional Boxplots for Multivariate Curves
Zhuo Qu,
Marc G. Genton
Abstract:This paper introduces the sparse functional boxplot and the intensity sparse functional boxplot as practical exploratory tools that make visualization possible for both complete and sparse functional data. These visualization tools can be used either in the univariate or multivariate functional setting. The sparse functional boxplot, which is based on the functional boxplot, depicts sparseness characteristics in the envelope of the 50% central region, the median curve, and the outliers. The proportion of missi… Show more
