Is there a way to create a bland-altman analysis and have the mean be based on a theoretical value?

So I have two trials of data and I want to analyze how far they are away from 0.667, is there a way to make 0.667 my x-line?

Re: Is there a way to create a bland-altman analysis and have the mean be based on a theoretical value?

As conventionally understood, a Bland-Altman analysis is for testing the level of agreement between two different ways of measuring the same thing. See, for example:

http://www.stattutorials.com/SAS/TUTORIAL-BLAND-ALTMAN.htm

https://en.wikipedia.org/wiki/Bland–Altman_plot

https://community.jmp.com/docs/DOC-6171

So using this approach doesn't seem to stack up with your desire to 'analyze how far each trial is away from 0.667'.


Can you describe a little more how your data was measured, or better yet, supply a sample?
