calculate_concentration: Building a proxy concentration matrix.

Description Usage Arguments Value

Description

If we don't have the true concentration matrix of the data rows calculated, but at least have the Z scores of individual rows, (unrealistically) assuming independence and calculating the concentration matrix from those is still better than nothing (i. e. the identity matrix).

Usage

1

Arguments

data

The data containing at least the expected values of f statistics (column D) and possibly also products of expected values and f statistics divided by standard deviations of (the Z scores, column Z.value).

Z.value

Tells whether the Z scores are available or should we just use the identity matrix.

Value

The Cholesky decomposition of the inverted covariance matrix.
