Least square means stata

Least square means are means for groups that are adjusted for means of other factors in the model. Imagine a case where you are measuring the height of 7th-grade students in two classrooms, and want to see if there is a difference between the two classrooms. You are also recording the sex of . If the model is estimated by least squares (OLS in the linear case), this is the LS-mean (of treatment, in this case). For a reference on implementation (in R) see this pdf it also covers LS-means . 2vwls— Variance-weighted least squares regress with analytic weights can be used to produce another kind of “variance-weighted least squares”; see Remarks and examples for an explanation of the difference. Options Model noconstant; see[R] estimation options.
