PCAMethods {GeneSelector} | R Documentation |
Aggregation over different perturbed datasets can be performed using
one of the methods beginning with Aggregate
.
For aggregation with respect to different ranking procedures, principal
components analysis is used in the following manner: For each gene,
the rankings obtained from, say K
, procedures are stored in
a p x K
matrix, where p
is the total number of genes.
The different ranking procedures are intepreted as variables.
The first principal component is used to form an aggregated ranking.
