SAS 9.3 documentation for procedures.
SAS 9.3 language documentation (for data steps)
Creativity.sas Randomization and T tests comparing
means from two independent samples.
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.
Hamburger.sas Code to do
nonparametric 2 sample test (Wilcoxon rank sum test).
calcmeans.sas Code to calculate
averages over subsamples
Dietall.sas
Calculating log transformations, ANOVA and
'After the ANOVA' analyses: linear contrasts, multiple comparisons
fdr.sas False discovery rate adjustment, starting
with p-values. Running multiple analyses and saving the p-values.
readcharacter.sas SAS-specific issues reading character
data.
meat1.sas Linear regression using proc glm or proc reg.
Estimating slope and intercept.
meat.sas More linear regression: confidence and prediction
intervals, ANOVA lack of fit test, various bells and whistles in proc sgplot.
levene.sas Program to implement
Levene's test of equal variances (not discussed in lab)
p-values.sas Using SAS
to compute two-sided p-values from T statistics, p-values
from F statistics, and quantiles of a T distribution (not discussed in lab).
brain.sas scatterplot matrices, Multiple linear regression using
PROC GLM and PROC REG.
corn.sas
Calculating polynomial terms.
light.sas
Constructing indicator variables. Fitting multiple regression
models with indicator variables. Note: Uses light.txt data file.
