dLRs: Caculate the DLR Spread.

In ADM3: An Interpretation of the ADM method - automated detection algorithm.

Description

Calculates the "DLR spread" - derivative log2 ratio spread.

Usage

dLRs(x)

Arguments

x	- vector of log ratio values.

Details

Calculates the probe-to-probe log ratio difference of an array. This is a noise estimation which is robust to outliers.

Value

The derivative log2 ratio spread.

Note

A value used to compute the minimum log ratio difference needed to detect an outlier.
