adjboxStats: Statistics for Skewness-adjusted Boxplots

Description

Computes the statistics for producing boxplots adjusted for skewed distributions as proposed in Hubert and Vandervieren (2004).

Usage

adjboxStats(x, coef = 1.5, a = -4, b = 3, do.conf = TRUE, do.out = TRUE)

Arguments

x

~~Describe x here~~

coef

~~Describe coef here~~

a

~~Describe a here~~

b

~~Describe b here~~

do.conf

~~Describe do.conf here~~

do.out

~~Describe do.out here~~

Value

• A list with the components
• stats
  a matrix, each column contains the extreme of the lower whisker, the lower hinge, the median, the upper hinge and the extreme of the upper whisker for one group/plot. If all the inputs have the same class attribute, so will this component.
• n
  a vector with the number of observations in each group.
• coef
  a matrix where each column contains the lower and upper extremes of the notch.
• out
  the values of any data points which lie beyond the extremes of the whiskers.
