Bitaliasing of a CRP matrix

Unlike Uniformity, it does not make sense to calculate the bitaliasing of a single bit vector. Thus, bitaliasing only works on 2D matrix.

Usage

bitaliasing(crps)

Arguments

crps

A bit vector or a 2D CRP matrix

Value

The normalized Hamming weight of each column.

Details

Like Unformity, this function assumes that the CRPs are supplied in a 2D matrix, where each row corresponds to a device and each column corresponds to a CRP.

Bitaliasing measures the distribution of 1s and 0s for a single CRPs across all devices.

$$Bitaliasing(c) = \frac{1}{\#D} \sum_{d \in D} r_c$$
