Method comparison, method evaluation and agreement
Method comparison & evaluation
MedCalc contains the following statistical procedures specifically for Method comparison & evaluation:
Agreement & responsiveness
For analyzing agreement and responsiveness, MedCalc offers:
ROC curve analysis
MedCalc is the most commonly used software for ROC curve analysis in biomedical literature.
See: ROC curve analysis features
of MedCalc and MedCalc manual: ROC curve analysis
MedCalc calculates reference intervals using the Normal distribution, a non-parametrical percentile method, and optionally a robust method
as described in the CLSI Guidelines C28-A3.
See MedCalc manual: Reference interval
The control chart is a graph used to study how processes or measurements change over time with data plotted in time order. Rules are applied (Westgard et al., 1981) to automatically signal when the process is out of control.
See MedCalc manual: Control chart
The Youden plot is a graphical method to analyse inter-laboratory data, where all laboratories have analysed 2 samples. The plot visualises within-laboratory variability as well as between-laboratory variability.
MedCalc draws the original Youden plot and common variations, including an adaptation for non-comparable samples.
