CPD: CPD

In msImpute: Imputation of label-free mass spectrometry peptides

Description

Spearman correlation between pairwise distances in the original data and imputed data. CPD quantifies preservation of the global structure after imputation. Requires complete datasets - for developers/use in benchmark studies only.

Usage

CPD(xorigin, ximputed)

Arguments

xorigin	numeric matrix. The original log-intensity data. Can not contain missing values.
ximputed	numeric matrix. The imputed log-intensity data. Can not contain missing values.

Value

numeric

Examples

data(pxd007959)
y <- pxd007959$y
y <- y[complete.cases(y),]
# for demonstration we use same y for xorigin and ximputed
