I have been looking for an errors-in-variables regression to use for method comparison experiments. I have found a method by Williamson which seems to be the standard method for this problem. My question is how I test the hypothesis b=0. I have the slope and se as calculated in the Williamson paper, however no formula is given for computation of the hypothesis test. In standard linear regression I would normally use a t-distribution but using Monte Carlo simulations it seems that using the t-distibution leads to a conservative rejection of the null hypothesis? Anyone able to help? Dr L Green.
