Webb20 sep. 2024 · I was wondering on Stata is there an option to do this test (both the equal variance of 2 subsamples and unequal versions of test) but with the mean of the "1" group - mean of "0" group as opposed to how it is now which is: mean (0)-mean (1). Thanks in advance. Tags: None Clyde Schechter Join Date: Apr 2014 Posts: 25709 #2 06 Sep 2024, …

WebbT-test Stata Annotated Output. The ttest command performs t-tests for one sample, two samples and paired observations. The single-sample t-test compares the mean of the sample to a given number (which you supply). The independent samples t-test compares the difference in the means from the two groups to a given value (usually 0).
