CoxBetaModel: Cox-Beta Model

Description Usage Format Usage Methods

Description

Regression beta coefficients are use for building a weighted distance measure between the learning and verum data set. The learning data set is used for learning the Cox model and use the obtained weights for calculating a (n x m)-distance matrix, where n is the number of cases in the learning data set and m is the number of cases of the query data. This distance matrix can then be used for cluster analysis or for getting for each case in the query data k (=1,...,l) smilar cases from the learning data. The rms-package is used for model fitting, variable selection, and checking the assumptions. If query data is ommitted, a n x n- distance matrix is returned.
