### Description

A dataset containing the Sample Ids from TCGA tumor purity measured according to 4 estimates attributes of 9364 tumor patients

### Usage

    Tumor.purity

### Format

A data frame with 9364 rows and 7 variables:

Sample.ID

  Sample ID from TCGA barcodes, character string

Cancer.type

  Cancer type, character string

ESTIMATE

  uses gene expression profiles of 141 immune genes and 141 stromal genes, 0-1 value

ABSOLUTE

  uses somatic copy-number data (estimations were available for only 11 cancer types), 0-1 value

LUMP

  (leukocytes unmethylation for purity), which averages 44 non-methylated immune-specific CpG sites, 0-1value

IHC

  as estimated by image analysis of haematoxylin and eosin stain slides produced by the Nationwide Childrens Hospital Biospecimen Core Resource, 0-1 value

CPE
