Hi,

What is the best statistical method to compare a measurement method with a criterion method?  I know that there is some controversy concerning the use of Bland-Altman plot and I would rather use Intra-Class Coefficient correlation.  Unfortunately, it seems there are different types of ICC and I am a bit confused about which one to select.

We are comparing results for total energy expenditure measured with a portable apparatus with results obtained with the doubly labelled water method.

Thanks for any statistical advices,
