Biplots of fuzzy coded data [PDF]

A biplot, which is the multivariate generalization of the two-variable scatterplot, can be used to visualize the results of many multivariate techniques, especially those that are based on the singular value decomposition.

Fuzzy midpoint–based imputation methods for non-parametric survival estimation with interval-censored data

Frontiers in Applied Mathematics and Statistics
The analysis of failure time data frequently encounters situations in which the exact time of event occurrence is unknown but is known to lie within a specified interval, resulting in interval-censored data.
