[Statistical analysis of a file of angiologic data on a micro- computer. Discriminant analysis of occlusive impedance...

The statistical analysis by multidimensional analysis of the data of a computerized file should lead to the improvement of the quality of the examinations. A discriminant analysis of the data of occlusive impedance rheoplethysmography allows a global analysis of all of the indices, by taking into account both their absolute values and their relative values. This results in a better compromise between the sensitivity and the specificity. The graphic representation gives an immediate conclusion and allows the functional outcome to be monitored.
