Z-Score Normalization - cBioPortal

Distribution based on diploid samples only The expression distribution for unaltered copies of the gene is estimated by calculating the mean and variance of the expression values for samples in which the gene is diploid (i.e.value is 0 as reported by discrete CNA data).We call this the unaltered distribution.If the gene has no diploid samples,then its normalized expression is reported as NA.Standardize or Normalize?
