Statistical inference
In addition to descriptive statistics, PROC UNIVARIATE
generates output for inference such as:
One sample t-test, sign-test and signed rank test; (the latter 2
tests can be regarded as non-parametric form of the one sample
t-test)
Confidence intervals for the mean and variance (assuming the
underlying population is normally distributed)
Formal tests for assessing whether the distribution is a normal
distribution or not
These are requested through the PROC UNIVARIATE
statements options
MU0, CIBASIC, ALPHA, NORMAL
