We propose a new nonparametric test for component independence which is based on application of data compressors to ranked data. For two-component data sample the idea is to break the sample in two parts and permute one of the components in the second part, while leaving the first part intact. The resulting two samples are then jointly ranked and a data compressor is applied to the resulting (binary) data string. The components are deemed independent if the string cannot be compressed. This procedure gives a provably valid test against all possible alternatives (that is, the test is distribution-free) provided the data compressor was ideal.
