Abstract.
VARIABLE SELECTION IN QSAR, The process of building mathematical models
in quantitative structure-activity relationship
(QSAR) studies is generally limited by the size of the dataset used
to select variables from. For huge datasets, the task of selecting a
given number of variables that produces the best linear model can be
enormous, if not unfeasible, In this case, some methods can be
used to separate good parameter combinations from the bad ones. In
this paper three methodologies are analyzed: systematic search, genetic
algorithm and chemometric methods. These methods have been exposed and
discussed through practical examples.
