Abstract

The program DISBAR is particularly adapted to medical data which often concern several measurements of different types (mixed variables) collected on patients divided into 2 groups according to a binary response variable such as survival or non-survival. DISBAR leads to a simple geometrical representation of the observations providing an easy allocation rule for a new case. The computer time required to run the program DISBAR is negligible in comparison with the one necessary to perform any other discriminant analysis of binary variables. DISBAR combines in practice computational facility with good results and easy interpretation.

摘要

DISBAR程序特别适用于医学数据，这些数据通常涉及对根据二元响应变量（如生存或非生存）分为两组的患者进行的几种不同类型（混合变量）的测量。DISBAR能对观测值进行简单的几何表示，为新病例提供了一个简单的分配规则。与对二元变量进行任何其他判别分析所需的时间相比，运行DISBAR程序所需的计算机时间可以忽略不计。在实际应用中，DISBAR将计算便利性与良好的结果和易于解释相结合。
