I have 4 repeat measurements on a variable 2 using method 1 and 2 using
method 2 over 50 patients. I was going to take mean values and then use
either Lin's concordance or Bland-Altman to compare them. However it strikes
me that I might be losing information doing this and that using repeated
measures anova might be more useful. Unfortunately I cannot work out the
correct syntax.
anova sn pat x, repeated(x) does not take into account that the values 1 & 2
of x refer to method 1 and 3,4 refer to method 2.
I would be grateful for some advice on the syntax - or the appropriateness
of this approach.
Janet
