Sep 20,  · Hi Carlo one quick question I also wanted to ask with regards to the means difference test. In my regression model I use total assets as a proxy for firm size, where normally in literature they use the natural log of the assets to proxy for firm size, which is what I do when I estimate my models. There is no svy: ttest command in Stata; however, svy: mean is a “true” estimation command and allows for the use of both the test and lincom post-estimation commands. It is also easy to do a t-test using the svy: regress command. We will show each of these three ways of conducting a . Independent t-test using Stata Introduction. The independent t-test, also referred to as an independent-samples t-test, independent-measures t-test or unpaired t-test, is used to determine whether the mean of a dependent variable (e.g., weight, anxiety level, salary, reaction time, etc.) is the same in two unrelated, independent groups (e.g., males vs females, employed vs unemployed, under
