Dear list members,
I have 4 estimates (each estimate have its se or variance), 2 from
treatment units and 2 from control units. I want to do a t-test with
inverse variance weighting to compare treatment vs control units.
Does anybody knows if there is an R function to do this type of analysis?
I am trying to get the confidence interval of the difference (I am not
interested in the t and P values).
Thank you very much in advance.
Best,
Manuel Spínola
