SAS programs that have been discussed in lab (or in class) are included
here.

**Programs from Lab on 22 Aug 2012 **

window, and how to assign that bit of code to a key or toolbar button.
readdata.sas Code to read data into SAS
in various ways
tomrand.sas Code to do a two-sample
randomization test using PROC NPAR1WAY with SCORES=DATA.
tomt.sas Code to do a two sample t-test

**Programs from Lab on 5 Sept 2012 **

Pairedt.sas Code to do a paired t
test in either PROC MEANS or PROC UNIVARIATE. PROC MEANS also
computes confidence interval for mean difference. PROC UNIVARIATE
also computes the nonparametric sign and Wilcoxon signed rank tests.

variables and construct a residual plot using proc glm.
