Subject: st: testing linear combination of means
Dear Statalist members:
Suppose there are four variables: var1, var2, var3, var4. I need to test
whether
0.5 * [mean(var1) - mean(var2)] - 0.5 * [mean(var3) - mean(var4)]
is significantly different from zero.
Is there any idea how to perform the test?
Thanks in advance,
Ivica
