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.
