Method comparison / Agreement
Fit Y on X
Regression of Y on X describes the linear relationship between the methods.
Ordinary linear regression
Ordinary linear regression fits a line describing the relationship between two variables assuming the X variable is measured without error.
Deming regression
Deming regression is an errors-in-variables model that fits a line describing the relationship between two variables. Unlike ordinary linear regression, it is suitable when there is measurement error in both variables.
Passing-Bablok regression
Passing-Bablok regression fits a line describing the relationship between two variables. It is robust, non-parametric, and is not sensitive to outliers or the distribution of errors.
