First release of a new free software : Method Validator
Method validator is a statistical programme designed for comparing
analytical techniques in clinical laboratories. Its aim is to provide
a simple tool which can be used intuitively without any training. It
makes use of conventional statistical techniques :
- Difference plot (with or without log transformation).
- Normal linear regression (weighted or unweighted).
- Deming regression (weighted or unweighted).
- Passing and Bablok non-parametric methods (comparison test and
estimation of the regression).
The graphical tools have been studied in depth to simplify the
plotting of data. Import/export functions are provided to allow
exchange of data with a spreadsheet or copy/pasting of the graphs in a
A random number generator allows various experimental situations to be
simulated by changing the analytical CV of each method and the
distribution of data.
