Dear Stata list
I have two groups with two means and different standard deviations (SD), and the latter is the problem.
Using the zcalc program, se description below, i can calculate a z-score between the groups if the SD was the same in both groups.
How do i calculate the normal value (z-score) for a measurement method when the groups have different means?
Thank you
Lars
The zcalc option from findit:
---------------------------
Description
-----------
zcalc is a silly little program that computes z-scores.
If you provide the arguements x mean sd, zcalc
computes a z-score for observations. If you
provide the arguements mean mu sd n in the arguement
list zclac computes a z-score for sample means.
