Method Detail

quantileNormalize

public DoubleMatrix<R,C> quantileNormalize(DoubleMatrix<R,C> matrix)

Rows with all missing will not be returned. Otherwise, missing values are imputed, used for estimating quantiles, and then replaced with missing values at the end.

Note that the Bioconductor implementation deals with missing values differently, and in a much more complex way. Therefore this gives different answers in the missing value case from Bioconductor (normalize.quantiles).

Parameters:

matrix -

Returns:
