Library: tware
See also: twrandomsample twpvalue twnormalize twpearson twclt twlinreg

Quantlet: tw1d
Description: The teachware quantlet tw1d shows a histogram of the user-defined data and offers an interactive visual analysis of this data by means of box plots (for mean and median) and QQ-plots. Transformations may be applied to the data in order to study the change in distribution and box plots.

Reference(s):

Usage: tw1d({x})
Input:
x n x 1 vector containing the user defined data

Note:

Example:
; load teachware library
library("tware")
; pre-define asymmetric data
x = exp(normal(100))
; call tw1d teachware quantlet
tw1d(x)

Result:
A two-part window with the histogram of the actual data
distribution in the upper part and a jittered dot plot
of the data in the lower part of the display. The
histogram and the dot plot changes with the chosen
transformations.
