Dear List
This might be a bit more of a stats question than a stata question.
I am about to do a cross sectional study comparing two groups regarding a measured continous variable.
I know the the variance of the measurement. No one has ever investigated these groups before using this or similar machines. For practical reasons i only have a limited number of participants available for this project. I am now wondering what the minimal detectable difference between the two groups are with the number of participants i have available.
I will use a t-test (paired, seeing the two groups are matched)
How do i calculate this using stata?
