cor.me.matrix {MeasurementError.cor}R Documentation

A function to calculate measurement error estimates for all pairs of genes given by the matrix

Description

Given a matrix ( p x n) for observed values of p variables and a corresponding matrix for their standard errors, the all pairwise measurement error estimates for true correlations are returned

Usage

cor.me.matrix(exp, se)

Arguments

exp observed value marix
se standard error matrix

Details

Value

The final estimates for true correlation (i.e. cor.true) from the measurement error model

Note

The function involves using quasi-newton for linear optimization, "BFGS" is the only implemented method now. Refer to cor.me.vector for more details.
