compute the precision at given sizes of retrieved genes
Description
Given a vector of sizes of retrieved genes, for each size k, select the top k genes with smallest p values and compute the precision from the retrieved genes and the true positive genes.
Usage
FindPrec(pvalue, ind,topk)
Arguments
pvalue |
A vector of p values, one for each gene, with length m |
ind |
A vector of indices that the corresponding gene are true positive |
topk |
A vector of integers ranging from 1 to m , length of retrieved gene list |
Value
prec |
A vector of precisions at given sizes of retrieval. |
