Compare analytical methods to determine bias and comparability using Deming regression & Weighted Deming regression.
Analyse-it includes Deming regression and Weighted Deming regression so you can compare two analytical methods to determine bias (systematic error). Unlike linear regression, Deming regression allows measurement error (imprecision) in both the X and Y variables so is ideal for comparing clinical methods.
Analyse-it uses the latest algorithms from widely respected international journals. Cornbleet and Gochman is used to calculate Deming regression, and the latest iteratively re-weighted procedure described by Linnet  is used to calculate Weighted Deming regression. Standard errors and confidence intervals use the jack-knife method .
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.
