中文摘要	in chemistry for chemical analysis of a multi-component sample or quantitative structure-activity/property relationship (qsar/qspr) studies, variable selection is a key step. in this study, comparisons between different methods were performed. these methods include three classical methods such as forward selection, backward elimination and stepwise regression; orthogonal descriptors; leaps-and-bounds regression and genetic algorithm. thirty-five nitrobenzenes were taken as the data set. from these structures quantum chemical parameters, topological indices and indicator variable were extracted as the descriptors for the comparisons of variable selections. the interesting results have been obtained.
