Compare analytical methods to determine bias and comparability using Passing-Bablok regression.
Analyse-it includes Passing Bablok regression so you can compare two analytical methods to determine bias (systematic error). Unlike linear regression, Passing Bablok regression is ideal for comparing clinical methods because it allows measurement error (imprecision) in both the X and Y variables, does not assume measurement error is normally distributed, and is robust against outliers.
Analyse-it uses the latest algorithms from widely respected international journals, including Passing Bablok regression [1, 2, 3] for method comparison and method conversion.
Analyse-it is the leading statistics software for Microsoft Excel.
First released in 1997, Analyse-it surpasses traditional statistical software in ease of use, features and price. Over 25,000 customers now rely on Analyse-it for in-depth statistical analysis and visualization in Excel.
