Standard error of mean stata
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.

WebbCalculation of se (prediction error) If we change the variable p o p to p o p − 1029, then θ ^ is reported as the intercept estimate: /* Stata */ gen pop2 = pop - 1029 reg fuel pop2 You see that the reparameterizated model f u e l = θ + β 1 ( p o p − 1029) + u gives θ = β 0 + 1029 β 1 so the intercept estimator θ ^ is your predictor.

Now, the means after FE are simply E [ Y D = 0] = α and E [ Y D = 1] = α + β, because the intercept in Stata fixed effects regression is just the mean. But how do I get the standard deviations? Groups may not have the same number of observations.
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).
