Thie folder contains one SAS file, one R file, and three data files. 
These are supplementary materials to the article "An Overview of Applied Robust Methods" 
by Ke-Hai Yuan and Brenna Gomer.

The SAS file (RTRANS_Mardia.sas) is a sas iml program for conducting robust transformation, 
using Mardia's open-closed-book test score data as an example.

The R file (RTRANS_Mardia.R) is an R version of the sas iml file, to conduct 
robust transformation, using Mardia's open-closed-book test score data as an example.

Figure1_2_3.dat is an artificial data used to draw the plots in Figures 1, 2 and 3.

The file Fang.dat contains the data from  Fang el al. (2020).
The 5 variables in the file are
gender (female=0, male=1), cyber bullying (square root transfromed by Fang),
callous unemotional, moral disengagement, empathy. 
It is used to compute the results in Tables 1, 2, 3 & 7; and to draw the plots in Figures 4 & 5.

The file Mardia.dat contains the data from Table 1.2.1 of Mardia, Kent and Bibby (1979).
The 5 variables are scores on mechanics, vectors, algebra, analysis, and statistics. 
The first two subjects were tested with closed-book exams
and the last three were tested with open-book exams. 
It is used to compute the results in Table 4, 5 & 6; and to draw the plots in Figures 6 & 7.
