RegisterMethod A of EMA [Software]
Hi All!
I was trying to calculate 90% CI using excel and found difference with the reported values.
I am using below formula for getting margin of error.
Margin of error=CONFIDENCE.T(ALPHA, STD_DEV,SIZE)
Where ALPHA=1-%CI=0.1
Is this the correct approach?
Thank you,
Divyen
