The Bag-and-Whisker Plot: A New Bagplot for Bivariate Data
Shenghao Qin, Bowen Gang, Tiejun Tong +1
The bagplot, also known as the "bag-and-bolster plot", is a notable extension of the boxplot from univariate to bivariate data. Although widely used, its practical application is h…
ChauBoxplot and AdaptiveBoxplot: Two R packages for boxplot-based outlier detection
Tiejun Tong, Hongmei Lin, Bowen Gang +1
Tukey's boxplot is widely used for outlier detection; however, its classic fixed-fence rule tends to flag an excessive number of outliers as the sample size grows. To address this,…
Unifying Boxplots: A Multiple Testing Perspective
Bowen Gang, Hongmei Lin, Tiejun Tong
Tukey's boxplot is a foundational tool for exploratory data analysis, but its classic outlier-flagging rule does not account for the sample size, and subsequent modifications have…
When Tukey meets Chauvenet: a new boxplot criterion for outlier detection
Hongmei Lin, Riquan Zhang, Tiejun Tong
The box-and-whisker plot, introduced by Tukey (1977), is one of the most popular graphical methods in descriptive statistics. On the other hand, however, Tukey's boxplot is free of…
