Abstract EN
The aim of this research is to predict membership in two mutually exclusive groups of bronchitis cancer patients, and allocating new patients using Discriminant Analysis.
Discrimination is a multivariate technique concerned with separating distinct sets of objects (or observations) and with allocating new objects (observation) to previously defined groups.
The results showed 90 %, and 98 % of dead and alive patients were classified correctly.
Only 2 % and 10 % of dead and alive patients were misclassified population models.
We now assume that f1(x) and f2(x) are multivariate normal densities, the first with mean vector μ1and covariance matrix 1 and the second with mean vector μ2and covariance matrix 2.
The special case of equal covariance matrices leads to a particularly simple linear classification statistic.
